Hi I have two comboboxes, we'll call them Combo1 and Combo2. Combo1 has values of A, B, C, Combo2 has values however they are irrelevant. When value B is selected from Combo1, Combo2 is visible. When value B is unselected from Combo1, Combo2 is hidden. What I also need is Combo2 to be reset. I've tired to use Reset() in Combo1 in an if statement, however power apps says I can't do that action.

Anyone have an ideal of how I can reset Combo2 when a certain selection in Combo1 is unselected?

Try setting a variable to handle the reset.

In the Combo1 "OnChange" property, set a reset variable:

First set it true, and then false again.

Set(varResetCombo, true);
Set(varResetCombo, false);

Now, in the Combo2 "Reset" Property enter the variable: varResetCombo

That will reset Combo2.

Thanks that put me on the right path and I modified a bit and ended going with this and it works great because it wipes out combobox2 when the unique item in the list is deselected in combobox1:

If(
"Combo1 unique selected item" in combo1Var,
Set(
varResetCombo,
false
),
Set(
varResetCombo,
true
)
)
