i have a scenario List A has multi line of text field, i need to look up this in my List B. Sharepoint will not allow you to select multi line of text as look up , so i saved List A mulitline of text value as calculated filed and look up in List B.
But the problem is if i design the List B form in nintex and save the record, it saves however when i try to view/edit i get the following error. interestingly if i use out of the box sharePoint form , add/edit/view works perfectly fine.
is that a nintex error or sharepoint one?
can post a screenshot?
for the former one, open developer console and for errors reported.
for the later, you should get there a 'Correlation ID' that you can use to investigate the problem further in SP ULS logs.
