interpreted = N
texte = Please help. I'm currently using Webcatalog NT Version 2.1. I need to use the [showif] command to show some code, based on the argument of whether it has a value or not. Now this is not as straight forward as it sounds, because the cell can potentially contain data in the format of text or number.I've tried using all sorts of commands, but doesn't seem to work because some cells have numbers in and others have text in.What I need to do is to find out if webcatalog can test whether or not the cell has a NULL value.Help will be much appreciatedRichard Zammit, E-Commerce Developer, -------------------------------------------------------------- Internet UK Services LTD, Port Hamble Marina, Hamble, Hampshire, UK, SO31 4QD t: + 44 (0) 1703 452409 x 201 f: + 44 (0) 1703 458409 -------------------------------------------------------------- richardz@inter.net.uk, www.inter.net.uk Associated Messages, from the most recent to the oldest:
