Topic: FGetVar?

Subject: FGetVar?
Date Posted: October/24/05 at 6:43am

I noticed that when my Name field in the products db is set as MEMO I get "None" displayed in the shopping Cart "Description" field (i.e. VIEW Cart).. In trying to troubleshoot this, I noticed a variable/function in the code called FGetVar, which does some massaging of the data. What is this? I couldn't find out what this does.. eitehr way, changing Name field to TEXT fixes problem...

Thx
Jim
