In the Unload() of the form (MyForm1), place something like this:

LOCAL lcValue
lcValue = Thisform.lAdding

DO FORM MyForm2 WITH lcValue

In the INIT() of MyForm2, create a parameters statement

PARAMETER tcValue
ThisForm.lAdding = tcValue

This will set the property (assuming there is one, and it is a good idea to have it) of MyForm2, to the value of MyForm1. From there, you can reference the MyForm2 property, from anywhere on MyForm2.
