I have two tables, Collections and Restrictions, which are related via a unique ID string (CollectionID). For most of the records, the ID is numeric but for a few it's alpha. When viewing the Collection table, I have a script that when activated should display a dialog box showing related information from the Restrictions table. Not all collections have restrictions, so the script looks like this:

[color:blue]If [Restrictions::CollectionID]

Show Custom Dialog [ Title: Collection::collection_title&" -- "&Restrictions::restr_type; Message: Restrictions::restr_text; Buttons: "OK"]

End If

When the ID is numeric, it works great. When the ID is alphabetic, it doesn't work. Is the test I'm using only for numeric data? What do I need to change so that it works? Thanks!

Is the test I'm using only for numeric data?

Yes. Actually, it's for numeric data that's not empty or zero.

What do I need to change so that it works?

Try:

not IsEmpty ( Restrictions::CollectionID )

Well if it is alphanumeric it will work. But just alpha no. Instead use If [ IsEmpty ( Restrictions::CollectionID) ] to see if the field is not empty.

Yes. Actually, it's for numeric data that's not empty or zero.

A matter of wording only but sliding the word NOT in there might help.

Actually, it's for numeric data that's not empty or NOT zero.

I only mention it because I did a double-take when I first read it and someone else might misunderstand.

UPDATE: Or write it as: not ( empty or zero) :wink2:

Right, human language is not as precise as mathematical notation. For example, I did a double-take at your using "or" instead of "and" because:

not ( empty or zero ) = not empty and not zero

w00t! You guys are great (and speedy) -- works like a charm, thanks :
