How to pause a function?

[XJ900]

I have a function that executes until it runs into an inconsistency, then another form loads to supply the correct variable. The problem I am running into is that although the other form loads the primary form where the function is running continues to run. How can I pause the current function until the value is supplied from the form it calls?

Thanks

Show the form modally: form.show vbmodal.
