Hi there,
I have coded up some script to make some simple calculations for a form that I require. In outputting the script to get the form to fill out certain data I am getting the message ‘inifinaty’, that is untill I select the submit button again where it performs the next calculation and again to perform the following and so on.
I need to have the code loop itself I guess? Therefore when I click the submit button all of the statements would run, therefore the entire outputs being filled in.
Could anyone help with how I should loop this statement?
JavaScript

As I said the first section is working fine, but only when I keep pressing on the calculate button to answer the next queries.
Many thanks for your help.
