This should be a pretty simple answer to find but I haven't had any luck.

Here is what I have. I have 3 combo boxes. Each subsequent combo box is revealed when a selection is made in the previous combo box. All combo boxes have placeholder text.

Here is what the behavior should look like
Combo box 1(visible with no selection) > Combo box 2(hidden) > Combo box 3(hidden)
Combo box 1(visible with selection) > Combo box 2(visible with no selection) > Combo box 3(hidden)
Combo box 1(visible with selection) > Combo box 2(visible with selection) > Combo box 3(visible)

I'm pretty sure I need to use the Visible property and make it conditional on the value/status of the previous combo box but not completely sure how. What I have tried usually throws an error or does nothing.

Combo box 1 Visible property: true

Combo box 2 Visible property: CountRows(Combo Box 1.SelectedItems) > 0

Combo box 3 Visible property: CountRows(Combo Box 2.SelectedItems) > 0

Use this code in the Visible property of ComboBox2

!IsBlank(ComboBox1.Selected)

Then use this code in the Visible property of ComboBox3

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

@Future_Vision Assuming the first two are named Combo1 and Combo2, you would set the visibility of Combo2 to be

If(IsBlank(Combo1.Selected), false, true)

Then just duplicate this for the Combo3, but referencing Combo2.
