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' Quote Link to comment 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? Quote Link to comment Share on other sites More sharing options...
MasterACE14 Posted November 28, 2011 Share Posted November 28, 2011 You don't appear to be calling your function at all. Quote Link to comment Share on other sites More sharing options...
