Thanks. I ended up using the classes add/remove style, and it works well. However, a method that should be called on every page load is not working properly. I am sure that it's being called (tested with the console), but the removeValidators() method doesn't seem to work properly.
http://content.constructioninst.org/corporate_renewal.html On every page load, removeValidators will be called, which removes the "required" and "email" validation classes found within the jQuery object of the selector (first arg) if the caller's checkbox is checked. The problem is if, for example, I fill out the first section with its required fields, check the first box (which hides the bulk of the form), choose "Check" for payment, and submit. If I go back, while the hide/removeValidator method ("membersUnnecessary") is called and does indicate that the checkbox is checked (the same sections are hidden), I cannot re-submit the form: The validation classes are not removed. What can I do to fix this? I know that the code's a bit clumsy, but I can explain any specific parts if needed. Thanks, Thomas
