Cannot convert "Int" into string

Unity Engine
1

I’m getting this error with a script:

var guitextobject: GUIText; 

var bluescore: int=0; 
var limit: int=10; 

function addBlue(){ 
bluescore++; 


guiText.text = bluescore; 


} 
function Update(){ 
if (bluescore==limit) 
Application.LoadLevel("empty"); 

}

I get an error saying (topic). how can I fix this? EDIT: line 10

Try this instead:guiText.text = bluescore.ToString();
