OnChange issue

I have a OnChange formula on combobox 1 to reset combobox 2 when changes are made.

i also have a check to verify if both comboboxes are filled before you can move to the next page.

when both comboboxes are populated, you are able to click the "Next" button.

however, when you make a change in combobox 1, combobox 2 is reset, but the "Next" button is still available.

the statement remains false (only when i manually, fill and remove an option it changes)

is there any way to interact this?

Re: OnChange issue

Hi!

I hope I'm understanding correctly, that you just want the "Next" button visible if both comboboxes are filled. Depending on how you're checking that both combobox1 and combobox2 are populated, there could be a couple reasons.

For sake of simplicity, what I usually do, is in the visibility of the "Next" button, use:

!IsBlank(ComboBox1.Selected) && !IsBlank(ComboBox2.Selected)

^All this does is confirm that both comboboxes aren't blank. It should update as soon as combobox2 is reset.

Hope this helps!

Re: OnChange issue

Hello @jverdonk .

If I understand correctly, you issue is that you want "Next" button to not to be visible (or to change the display mode) if combobox is reset. (Note: reset does not mean your combobox is empty, maybe you have default selected values). Thus, you can use inside the visible property the code: !IsEmpty(ComboBox.SelectedItems)

On the other hand, if you want to check if any changes are made in the combobox2, use variables.

Hope this helps.
