I have a form with a subform.  The "Vendor" on the subform defaults to the
"Vendor" on the Main form (Vendor default = Parent!Vendor).  The "Vendor" on
the subform is a combo box.
The OnChange event of the subform.Vendor calls a Macro that has two
conditional statements that should either set a value of "3" in the
subform.status when the subform.Vendor <> the Parent!Vendor, or set the
subform.status to a value of "1" if the subform.Vendor = Parent!Vendor.
When the form comes up the subform.vendor is defaulted correctly to match
the "Vendor" on the main form.  Upon selecting a different Vendor from the
subform.vendor combo box, the macro runs and sets the correct value of 3 in
the subform.status control.  If I change the subform.vendor combobox back to
the original Vendor that matches the Main form, it does not change the
subform.status to a 1.  Single stepping the macro shows that it is evaluating
the condition as "false" even though the form is showing that the Vendor in
both the Main and subform are a match.
I have never used debug before, but tried that to get the value of the
OnChange control, but I do not have an example for a main and subform and
cannot get the syntax correct.
Any ideas why this is evaluating to false when the Vendor control is changed
a second time?
