Re: logic problem

Re-read my original email, I'm using mssql and not mysql. I'm sort of close to having it working with the sql statement i posted earlier and using PHP to figure out if the date has changed or not and to count the cardnum if the date hasn't changed. I'm getting a number that is different then the total number multiple visits by patrons, haven't checked with the registration person if the # I am getting is right or not, because for some of the very early dates when we were testing the equipment, it returns a count of 0 visits by type 1 card users, even though they have a count of 15 multiple entries that day, so something weird is still going on. i think i'm going to have to end up using a multidimensional array and having PHP loop through it or something...
