Ok I can't find the answer to my question. Its probably here somewhere already so forgive me if I repeat it my eyes are blurry after following about 80 pages of this.

1. I have zencart 1.3.9f
2. have installed the version 1.07

It works fine If I have the admin set to global enable tabs on. Then all the products descriptions have tabs on.

Maybe I misunderstand but I thought I could set that to off and then control individually which products have tabs and which ones don't simply by using the tags on a product by product description level, insuring I am using the text editor and not the html editor when I build the product description.

However if I set global enable tabs to off then individually take a product description and use the tags, eg, <!--%Product Description%--> nothing happens.
