Do not leave screen, if inputs are not acceptable

[HayoOellrich]

Hi !

I need a way to stop users from switching to next screen, when the screen inputs are not acceptable.

For example, I created a set of checkboxes, where at least one must be chosen.

How do I implement that (in SF 6.0.1) ?

Set the variable %PreventNextPage% to TRUE.
