We have a form with a zillion date fields that all have the same validation.
We're calling a function from a js library for the validation.
But I'd like to also store the validation message in a central spot, so we only have to update it once if needed.
Can anyone suggest a suitable way to do this?
I think you can store the message in TM as a property or datasource, then pull it from your form or even inject it as a prefill.
If you prefer to keep it in the form, maybe datafield or hidden field, and refer to it to display the error.
