Hi all, I have a problem that I need solving hope you can help point me in teh right direction. Ok I need to calculate a total of a variable amount I have created. I know how to do SQL sum totals, however this item is based on a calculation and not on a DB output. I have tried to put it in an array but still cannot get it to calculate. held in a while loop the variable is output ok echo round($reqprod); = OUTPUT DATA TO CORRESPONDING CELLS IN HTML I need to calculate all teh values held in ($reqprod) to output at the top row of the table? Any help would be superb thanks Sidders
