Test for Portal isempty()

[ejpvi]

This is probably an easy question, but I can't find the answer.

I have a script that as it runs, it populates another table, which I can see instantly on a portal.

What I want to add to the beginning of the script is a test. I only want the script to run if the portal is empty.

I know there is a isempty() function, but I am not sure how to use it.

Right now I have it say... go to Portal Row [first]

if(isempty(?)) where the question mark is, I am not sure what to put...

How do I test to see if it is empty?

You don't need to go to a portal row (or use a portal at all).

IsEmpty ( Related::Matchfield )

will tell you if there are related records or not.

Thanks, worked like a charm.
