I have a form that gathers subscription information for a client that they want a csv file to import into their system.  I run into problems because users will sometimes add a comma in one of the fields which then gets into the csv and throws eerything into an error.    Is there a way to block the entry of commas? I have most fields set up with formatting for phone numbers and such, but the text boxes are what is giving me an issue. For example, one user wanted to register the names of both the husband and wife and separated them with a comma.  This made the wife's name become the house address and everything shifted to the right from there.   There is already tons of conditional formatting and external code to get things to work the way the customer wanted, so I'm not real excited about more code to tack on unless it's really necessary.   If needed, here is the url:  https://swgmove2zero.com/nv/   Thanks for any help on this!
