Source Object Variable.

[Lethoric]

Greetings;

What I'm trying to do is build a Form consisting of a SubForm Control Object.

If Client pressess button "A", I want SubForm "A" to load, and when button
"B" is pressed, SubForm "B" to load.

Now, I was able to accomplish this by using

Form![Main Form]![SourceObject Name].sourceobject = "SubForm A"

This will load the Subforms into the Control area just fine, but I lose all
the Values I want changed to the SubForm before loading.

Is there a way that I can change the Values of a SubForm before loading it?
Otherwise, I can load, but I lose all values I wanted changed.
