hide blank line in label

In creating address labels, I wish to hide the address2 line when it is blank. Until now I’ve been able to do this by inserting a section, checking the ‘hide’ box and adding a condition such as Source.Post.Address2 EQ “”

For some reason, this has stopped working. I came across an alternative with instructions on hiding a blank paragraph which was far more convoluted and I didn’t get to work either.

So I don’t know what to do.

Incidentally, since tags are essential and especially the key ones, why not tell us so we don’t waste time with failed sends.
