it would be a simple one with only three fields:
"label" -Number of Shirts
"label" -Number of Colors on Front
"label" -Number of Colors on Back
"button" calculate total
"results" total: $xx per bag:$xx
total price would decrease based on the number of shirts (more volume) / increase based on the number of colors both front and back.
something i found online that is 100% what i want: http://zeustees.com/about-us
i tried to work with the .js from that website but it calls in some qq2.php page. so i haven't been able to replicate the solution. plus, i would assume that their price structure would be different than mine.
thank you in advance for your help
