Question

Multiple date field comparison

I have a form with multiple date fields (5) that need to be validated against one "first" date field. I haven't been able to get it to work with the scripts that I've found online.

Hopefully the screenshot that I'm including makes sense.

All of the date fields following "Date first case became ill" cannot be dates before that date.

I appreciate any help provided.

Have you tired to convert the date string to a format that is can be sorted?

One could also convert the dates to a unique numeric value where the value of each day maps to a ascending number line.

Thanks for your input. These sound like great ideas but I wouldn't know how to do that.

Could I be overcomplicating things and just need something in each subsequent field that checks its value against the first field?
