I have code that takes a drawing number and figures out witch folder it resids in. I go trhough a few do cases for this. I have several places where this code is used so I wanted to create it in a program or procedure that all places could use it. So I send my drawing number as a parameter and my conventional way would be to set a Public variable and then back in my calling program use that result. But now with what you and Jim have taught me I thought I could create a custom Property in my calling form, sent that as a second parameter and have the prog assign a value to it. But I can't get the property to respond.
