Thanks for the explanation!

In case it helps anyone else, it doesn't seem to matter which tablename you put into the perl ITL, so if you stick the following in your catalog.cfg you can use $Tag->data for any table in all ActionMap subs and [calc] blocks.

AutoLoad [perl products][/perl]

On a side note, it seems strange to me that catalog UserTag subs can use the $Tag->data without any issue. The code must run in a slightly different Safe container I suppose.

Cheers!
