Button not executing function. C#

Question

I have a button that i would like to call a specific math function with. I placed Debug.Log messages to test what was going on. It appears that The button is not even calling the function because when i click it, the very first debug.log(3) for that function doesn't show up in the console.

Here is a screen shot and my script. I feel like i may have setup the script incorrectly because i am a newbie, but it should still call the Debug.Log(3) right?

I get Debugs 1 and 2 but not 3. I commented out the rest of my math function to test. Screenshot at bottom. using UnityEngine; using UnityEngine.UI; using System.Collections; using System;

 public class Calculations : MonoBehaviour {
     
     public GameObject textField_1;
     public GameObject textField_2;
     public GameObject textField_3;
     public Text Result;
     InputField t1;
     InputField t2;
     InputField t3;
 
     void Start()
     {
         Debug.Log (1);
         t1 = textField_1.GetComponent<InputField> ();
         t2 = textField_2.GetComponent<InputField> ();
         t3 = textField_3.GetComponent<InputField> ();
         Debug.Log (2);
     }
 
     
     public void Product() {
         Debug.Log (3);
         double a = Convert.ToDouble(t1.text);
         double b = Convert.ToDouble(t2.text);
         double c = Convert.ToDouble(t3.text);
         double d = a / 2;
         //double e = d * d;
         //double f = (e * 3.14) / b;
         Result.text = d.ToString ();
     }
     
 }

UPDATE: I just created a new button and applied the calculations script to it and added everything in the inspector. I get the Debug.log(3) but I also get an error. Here it is

FormatException: Unknown char: r System.Double.Parse (System.String s, NumberStyles style, IFormatProvider provider) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System/Double.cs:209) System.Double.Parse (System.String s) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System/Double.cs:180) System.Convert.ToDouble (System.String value) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System/Convert.cs:983) Calculations.Product () (at Assets/Script/Calculations.cs:28) UnityEngine.Events.InvokableCall.Invoke (System.Object[] args) (at C:/buildslave/unity/build/Runtime/Export/UnityEvent.cs:110) UnityEngine.Events.InvokableCallList.Invoke (System.Object[] parameters) (at C:/buildslave/unity/build/Runtime/Export/UnityEvent.cs:574) UnityEngine.Events.UnityEventBase.Invoke (System.Object[] parameters) (at C:/buildslave/unity/build/Runtime/Export/UnityEvent.cs:716) UnityEngine.Events.UnityEvent.Invoke () (at C:/buildslave/unity/build/Runtime/Export/UnityEvent_0.cs:53) UnityEngine.UI.Button.Press () (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/Button.cs:35) UnityEngine.UI.Button.OnPointerClick (UnityEngine.EventSystems.PointerEventData eventData) (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/UI/Core/Button.cs:44) UnityEngine.EventSystems.ExecuteEvents.Execute (IPointerClickHandler handler, UnityEngine.EventSystems.BaseEventData eventData) (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/EventSystem/ExecuteEvents.cs:52) UnityEngine.EventSystems.ExecuteEvents.Execute[IPointerClickHandler] (UnityEngine.GameObject target, UnityEngine.EventSystems.BaseEventData eventData, UnityEngine.EventSystems.EventFunction`1 functor) (at C:/buildslave/unity/build/Extensions/guisystem/UnityEngine.UI/EventSystem/ExecuteEvents.cs:269) UnityEngine.EventSystems.EventSystem:Update()

Is there something wrong with my function? Why doesnt my other button do this?

Thanks in advance for help!!!

So i figured out that there was most likely a scripting error on my part. I reverted back to an old version and everything is working again even though that part stays almost the exact same. I dont need help anymore and thanks to those who did!

Seems like your input value to the Convert.ToDouble-Method is wrong.

You can use TryParse to avoid this:

 double a = 0;
 if (!double.TryParse(t1.text, out a))
     // t1.text can not be converted to double

Looks like that the problem is with your Text Fields ...

Make sure that you Text Fields have Numeric input.

  double a = Convert.ToDouble("any_string");   //Wrong .. 
 
 
 
  double a = Convert.ToDouble(9857);     //Right
 or
  double a = Convert.ToDouble("3423");    //Right

Are those random numbers you put in there? or do they have to be specific?

Then how is it supposed to realize i want the numbers from the text boxes/input fields? It just used the numbers i put in the parentheses

Use Convert.ToDouble(t1.text)

Input a number in text box

haha yes i realize this, but it wasn't working. I reverted back to an old version of my script and caught myself up. I think that there was some sort of error that i was unaware of going on because the old version doesn't change at all in that section. Thanks for the help anyway!
