Menu
I got this script at the moment it has the drop down menus but they are all the same, I need each to be differnt e.g first drop down menu to have differnt optionse i.e like choose cpu, for second menu choose motherboard. etc and also each drop down menu will not neccasarily have the same number of options, e.g 1st drop down menu may have 5, second may have 7 etc. This is a major snag in the script which I am having trouble editing, if you could help me do this last thing it would be finished, thank you 4 ne help. I have attached my edited script so far
