the code above is actually perfect, well it works anyway, only problemis that it doesn't actually seem to work, i can't get into theconditonal that groups the data together rather than it just creating anew table, wondered if anyone could help please, as i havne't got aclue what's wrong with it, especially as echoing out the data manuallyshows that it should be doing what i'm trying to do.

basically $grps_catidstore echo's out

4
4
4
8
8

and $grps_catergoryinfo =

4
4
4
4
8

now based on that the first three should be in one table (it'sextracting one groups_browse_cathead and one groups_browse_catfoot) butfor some reason it won't do it
