Thanks kgossen, yes I'm using SIMPL and I do know I need to do it through the programming. The problem I'm trying to figure out is the help file says the button layout signal needs a specific value, i.e. 1d, 2d etc to specify the specific button configuration. If i try to enter a 3d on the signal line the 3 turns into a underscore, and I'm assuming would cause a compile error anyways. My guess is the signal must need to connect to another symbol that has a analog input which lets you specify a value, just can't figure out which one. And as I said in my earlier post I can't seem to find any example programs that show how to do this.
