Trying to Construct a Popup

I was working with the information at the last class, trying to rebuild a database that has been giving me problems ever since it was converted from Panorama 6. So I tried constructing a form, and I wanted one of the text boxes to be a popup, using the tag popup:a,b,c, but nothing seems to happen. I have tried this with a new database with just on field, A, and simply constructing Apopup:a,b,c, but all I get is the Text Editor object.

Oops, sorry, I apparently broke that when I added the popupediting tag. I have now fixed it, but in the meantime there is a workaround – you can use the <menu:a,b,c> tag instead, it does the same thing.
