Simple problem - referencing objects by variable name

programming flash
1

I have a simple function that dynamically creates text fields. My text field name is referenced by var thisTextField. Problem is, when i try to do things with my text field, actionscript shoots back an error as such:

**There is no property with the name ‘text’.

**How am i supposed to apply properties to my object if my objects name is a variable?

function showProducts() {
    
    var products:Number = 0;
    var thisTextField:String = "product" + products + "_txt";
    
    for (var itemID in _global.rtsData[_global.rtsPos]["products"]) {
    
        this.createTextField(thisTextField,1,25,75,350,50);
        trace(thisTextField);
        thisTextField.autoSize = true;
        product+products+_txt.text = _global.rtsData[_global.rtsPos]["products"][itemID]["products_name"];

        products++;
            
    }    
    
    _root.products_mc.gotoAndPlay("fadeIn");
       
}
