Hi, All you need to do is run a query to your db to get the times. than use something like this: <?php // Multiplying with varaibles $factorA = .01; $factorB = number_format(system_value('usercount'), 0); $product = $factorA * $factorB + .25; echo $product; ?> What this one does is count a total number of user on the website, than use factorA and multiplies that with factorB + a certain value. But this won't bring it in-line to what you want, but you could run some code to work it out. (just divide by .60?) J Hi All I have two tables with columns of times that it took to perform tasks eg: 8:40 6:50 8:30 10:55 --------- 34:55 total time taken to complete the tasks in hours and minutes I am able to add the times with sql however I need to add the totals to cone up with a grand total and because of the makeup of the tables I cant use sql. I am there for going to have to use php code and this is where the problem comes in because in sql there is SEC_TO_TIME and TIME_TO_SEC functions that allow easy addition of the times but I cant find an equivalent in php. Does any one know of a way that I can add to times together in php.
