I have no java script experience, so I'm completely lost. Here's my problem. I have a check box that needs to perform a custom calculation. When the check box is checked, I need it to add 30 percent to a separate field that is a total of other fields. Ultimately, I have one field that is the total of 4 other fields, and underneath that field is another field for the added 30 percent. When the box is checked, I need it to automatically add 30 percent to the field that is allocated for the 30 percent added to the total. If this makes no sense, please forgive me. Any help would be greatly appreciated.
I'm assuming that since you are not a programmer that currently your calculation uses the built-in Sum? If you want to use the checkbox then you'll need to use a custom calculation script. There is no way around it.
