How to attach number to a TextField

I know this is a stupid question but I really need help. :slight_smile: I have a Number variable

var _num:Number;
_num = 1;

for ( var i:Number = 0; i < 10; i++)
{

num.text = _num;
_num++;
}

I know there is no point in this. But my question is how to attach Number to a TextField :slight_smile:
1067: Implicit coercion of a value of type Number to an unrelated type String.
How to cope with this problem :slight_smile:
