GUILayout.TextField doesn't accept inputs
Well, i'm pretty sure this is a common problem caused for insufficient knowledge, i tried veryfing other questions and threads but i don't get them at all because they all have always something more specific as, for example, making a button dissapear or showing again depending on a certain state and some other things like that, but my problem is more simple i think.
I'm trying to learn networking since i want to make my game multiplayer, and, like in survivors, have a dialog to start the game as the server and another dialog to connect to another server, in which i want to have a Text Field to write the IP Address into. I managed to get my preferred layout look, but, i can't type anything into the TextField, i read in other questions that i must make sure i'm not calling the content inside the textfield from any other function, so i only called it from function Start() to set it to a default value ("192.168.1.100", only to test the connection, because this is my private IP at the moment), and i also tried to delete this call from Start() so it wouldn't got changed never, but Unity says:
NullReferenceException: Object reference not set to an instance of an object
UnityEngine.TextEditor.ClampPos () (at C:/BuildAgent/work/7535de4ca26c26ac/Runtime/Export/TextEditor.cs:1185)

Menu Principal.OnGUI () (at Assets/Mis Scripts/Menu Principal.js:225)
That would mean that anytime i want to use a TextField, i can't leave it 'empty', isn't it?
I'll leave to you the hole code of my Main Menu (some parts are in Spanish, sorry about that):

There is only one TextField in script (line 221). It shouldn't be even drawn, because there is no position or scale. See TextField documentation and try to edit it.
You were right, now i understood and got the IP input field working, thanks a lot!
btw it looks you are new to unity. It is good to mark every answered question as closed.
This answer is wrong. GUIlayout don't need position or scale (it positions and scales it self). You just wrote it wrong, the correct way is:
StringVar = GUILayout.TextField (StringVar,#);
"#" representing the max number (an int) of characters the user is allowed to type inside the text field and "StringVar" the string variable you want to edit.
In the case of the line 221 it would be:
InputCustomIP = GUILayout.TextField(InputCustomIP,12);
Check GUIlayout.TextField for more information: GUILayout.TextField
"GUI.TextField" and "GUILayout.TextField" are two different things
