Hi all
Is it possible to force a field to become mandatory if a certain selection is made in a drop down list? If the selection isn’t made then the field is there but not mandatory?
For example, there is a drop down choice of A, B, C and D. The field SELECT is always shown but you don’t have to enter anything into it unless you select either choice C or D.
Is this possible and how would I go about it.
Thanks 
Just for clarification, you have a choice component and another entry component, and that second entry component is the one you want to be required or not?
For something like that I would create two entry components. One marked as required and another that isn’t. Then conditionally show each one depending on the value in your choice component.
Yep! What Jeff said is best practice. Use visibility conditions to show either a required field or a non-required field based on the screen —> value.
Hi Jeff
This is actually what I ended up working out to do. So for choice A and B I had field 1 display whixh was not mandatory. For choice C and D I had field 2 display and it was mandatory. But what I thien had was field 3 which wasn’t an input field by the user but rather by the submit button. On submit if choice was A or B I copied field 1 into field 2 ans 3. If choice was C or D I copied field 2 I to field 1 and 3. That way if the choice was ever changed, the change was reflected in “real” field 3. Hope that makes sense 
Might not be the right way to do it and I’m happy for advice on the right way but it seems to be working.
Oh great. I ended up doing that before Jeff advised but I took it a step further so that if choice was changed, the data in the field (because the fields would change) would update a master field per say.
I think I understand what you are saying, but what I would maybe do differently is have both the required and non-required entry components pointing to the same column in the table. That way you wouldn’t need a third field or any On Submit actions to copy things around.
Ohhhh yeah that makes sense! Thanks!
Oh that works much better! I over complicated because I didn’t realise you could ignore the red warning that says two fields pointing to same column. . Thank you!
