MasterACE14 Posted November 27, 2011 Share Posted November 27, 2011 I'll be honest, I haven't read the entire script. But you do have a typo near the start which is probably the issue: $_SESSION['quanity']=array(); //if there are no quantities selected, the array is empty should be $_SESSION['quantity']=array(); //if there are no quantities selected, the array is empty missing the first 't' in 'quantity' Link to comment https://forums.phpfreaks.com/topic/251869-function-trouble/#findComment-1291483 Share on other sites More sharing options...
mindapolis Posted November 27, 2011 Author Share Posted November 27, 2011 I fixed that problem but it didn't fix the main problem. am I passing $price right to the function?

MasterACE14 Posted November 28, 2011 Share Posted November 28, 2011 You don't appear to be calling your function at all. Link to comment https://forums.phpfreaks.com/topic/251869-function-trouble/#findComment-1291749 Share on other sites More sharing options...
