Hi everyone,

I have an App.
It is a checklist and if something is false, user should set the toggle to false AND should specify what is the issue in a dropdown with predefined options. The dropdown, as default is empty.
This same dropdown disappears when the toggle is true.

I want my "Next" Button (upper right corner) should only be available when any FALSE toggle has a selected item in its respective dropdown.
I tried some nested "ifs" and switches but could not make it work..

Does anyone have any suggestions?

Thank you in advance!

Hello, @danappwiz

No, the the items are not in a gallery.
I tried your second suggesting but it ends up in the same error i had at start:

I tried it only with 2 toggle and 2 dropdowns.

As you can see in the picture, this scenario should not show the next button.
FYI: in the Onchange property of each toggle i have a Reset(dropdown) comand to erase the dropdown selection.

If your checklist items are in a gallery you can use the following on the OnVisible property of the "Next" button :

If( CountRows( Filter( galleryName.AllItems, toggleName.Checked = false && !IsBlank(dropdownName.Selected) ) ) > 0, true, false )

If they are separate components then you would need a more complex formula on the OnVisible instead :

If( Or( And(toggle1Name.Checked = false, !IsBlank(dropdown1Name.Selected)), And(toggle2Name.Checked = false, !IsBlank(dropdown2Name.Selected)), ... ), true, false )
