Have applied that and I'm just getting a white page on Submit now (attached).
Can you please explain Unique Column, Key Column and Key value? The Help button on this dialog no longer loads a help page.
Unique column is the field we're checking against, right? In this case the e-mail address field. Key column is? The unique row ID? And Key value? Urggh...now I'm lost.
Whatever way I'm doing it, and I've tried a few, it's crashing the page.
Hope you can help. Thank you.
