Circular reference issue

Hi everybody

I'm building an easy data form app but I'm having an issue with a circular reference.

For the purpose of the exercise let´s say that I have 2 questions: Q1 and Q2.

The visible property of the Q2 it is based on the answer of the Q1(is a dropdown), if the user selects "yes" is true otherwise it is false (if(Q1.datacardvalue.selected.value="Yes",true,false). Now for the Q2 I also had in the form a checkbox that will not be visible for the user with the default property like this=if(Q2datacardvalue.selected.value="No",true,false) however the system shows me that this is not possible because this creates a circular reference with the visible property of the Q2.

Any ideas on a workaround for this?

Thanks in advance for any help you can provide.

I have two dropdowns, each with items

["Yes","No"]

dropdown 2 has a visibility of

Dropdown1.Selected.Value="Yes"

and a checkbox that has a default of

Switch(Dropdown2.SelectedText.Value, "No",true, Blank(), false, false)

Selecting Yes on dropdown 1 makes 2 appear, selecting no makes it disappear.

Selecting yes on dropdown 2, or not selecting anything at all on it (because it has not been shown) makes our chekcbox unchecked by default.Selecting No on it makes our checkbox checked.

I also threw this in the onchange of dropdown 1 to reset/clear dropdown 2 if you had already selected an answer on dropdown 2 and change dropdown 1 to no

If(Self.SelectedText.Value="No", Reset(Dropdown2))

Thank you!!
Actually, I didn't use this method for my problem, I figured out by using some variables that triggers with the onchange of each dropdown. However, I just use your method for another issue that was kinda the same and it worked perfectly!
