Masked Zip Code field losses data after moving to next field on screen

It sounds like there is an OnExit event or something attached to the field.  SetText may not be properly entering the routines around the data field and so, when the OnExit event fires, it does not preserve the data.  This has been my experience in the past with similar issues.



Does it work differently if you use "Keys" instead of "SetText"?

You could also make sure that you directly execute keys on the object if you call



<objectname>.Keys(xxxxx-xxxx)



The Keys method is part all recognized objects.  



Either way, glad it worked for you.

We found sys.keys("#####-####") works

thanks for the input
