Set Control Visibility Based On Tag Property

I have a userform which uses the tag property of the frame to determine whether a frame is visible (and hence the controls that reside within the frame). A frame contains three combo boxes, and six text boxes. The tag property of the frame matches the number of frames that are visible on the form, so that if the user selects five frames, frames 1 through five become visible and for all other frames visible = false. A frame contains all the data for a single entry. There can be up to fifty frames/ entries that are visible on the form depending on the user selection.

I want to use the visibility property to do two things: first the combo boxes are filled from an array after the user selects the number of frames (or entries). I only want to fill the comboboxes where the frame is visible. The second thing is that I have a function which uses the data from the text boxes and combo boxes as required arguments. Since these are required arguments, I will get a data mismatch error if I try to call it and the controls are empty. Therefore, I only want to call the function if the frame which houses the controls is visible.

Public Sub Visible1(Entry As String)
Dim ctrl As Control
For Each ctrl In UserForm2.Controls
If TypeName(ctrl) = "Frame" And ctrl.Tag <= Entry Then
With ctrl
.Visible = True
End With
Else
If TypeName(ctrl) = "Frame" And ctrl.Tag > Entry Then
With ctrl
.Visible = False.............
