[4.6 UI] Show text as an int variable error

Hello Unity Community!

I'm having troubles scripting a text in the new 4.6 UI, in trying to access the text in the script and make it shows an int variable. I think the script it's right but I can't understand why it doesn't work. Unity's console shows this error "BCE0022: Cannot convert 'int' to 'String'.". This is the script:

 var playerDamage : playerScript;
 
 var myText : UnityEngine.UI.Text;
 
 function Update () {
 
 myText.text = playerDamage.damageHit;
 
 }

I can't understand this because I can write the number in the text field in inspector and Unity doesn't give any error but I need to use my variable. The variable it's in another script but it's just a number which it's changing constanly.
