Thanks to all who have taken the time to reply.

I considered using a global variable to specify the index to the global asset group info array for FormC. I thought this would not work because I was thinking that the user may want to add assets to more than one asset group at a time. Thinking this through more I realize that this is not necessary. I could set the global variable used to index the global asset group info array, then show FormC as a modal form.

Thanks again for your attention and helping me to think this through!
