How do I make the the condition that PayeeProviderNum cannot be the same as ServiceProviderNum?

How do I make the the condition that PayeeProviderNum cannot be the same as ServiceProviderNum? I want an error to show before the form is submitted.

That's possible. You just have to create a show condition that shows a certain text e.g. a warning message whenever that field's value matches.

Here's how:

1. First, add a text or a warning message in your form using the Text tool.

2. Create a Show/Hide condition like the following:

As a result:

You can also add another DO action like hiding the submit button so they can't submit the form until they corrected the error.

Hope this helps!
