I am trying to pass a dataset variable to display a specific category. Inside the filterFunc I have the following code which does not seem to work:

// Search by category  
\_global.\_filter = “username”;  
var \_category:String = String(item.\_global.\_filter);  
var \_categoryID:Number = \_category.indexOf(“true”);  
if (\_categoryID != -1) {  
return true;  
} return false;

This does not work, but if I use the following code, it will work fine:  
var \_category:String = String(item.username);  
var \_categoryID:Number = \_category.indexOf(“true”);  
if (\_categoryID != -1) {  
return true;  
} return false;

I am assuming I have to transform the string to an object, similar to how you access a button, but cannot get the syntax right. For example, to access a button (id) from a variable you use:

```
var my_btn = Eval(_name + "_btn");
// Based on the onPress Event, fire the search term 
my_btn.onPress = function(evt:Object) {
        // Add functionality here
}

```

Any help would be appreciated, thanks in advance
