Proper use of NotifyChoice

Can anyone give an example of proper use of NotifyChoice procedure? I need from a document form on click of a regular button invoke a selection form of another document and then selected in that form document pass to the original form. From what I found in syntax assistant seems like the most suitable way to do it is through NotifyChoice(...) procedure.

Hello Peter,

nobody has answered you, so I'll try to do it.

for first, clarify me please: do you just want to  open the selection form, select some value there, and return this value back to the form from which the call was made?

That's right. I found solution to this problem already using ListValueChoice(...) event handler.
