Thanks much Scott, That was it, it requires a valid line of code.

>For #1, in your builder program you say you have two parameters, but I don't quite understand why you are referencing "THIS.MyObjectReference.WriteMethod..." If your textbox reference parameter is oTxt, then it seems like you should be referencing oTxt.WriteMethod(). FWIW, in my builders, I don't pass a reference to the selected object. Instead, I use something like this:
>
>

>=ASELOBJ(aControls)
>oSelField=aControls(1)
>oSelField.WriteMethod("RightClick","Wait Window 'TEST'")

>As for #2, you may be close there. Apparently, WriteMethod() only lets you create valid code in the method, so "Test" probably won't work. Try it with a valid line of code like "Wait Window 'TEST'".

>>>Luis,

>>>In my builders, I always use the WriteMethod to do it. While it is hidden in the PEM sheet, your builder should be able to access it at design time.
