Problem with Tabindex
 

I have a multipage userform which contains the following on Page 0 from top
left to bottom right:

Txt1, Frame1 containing Txt2,Txt3, Frame2 containing Txt4, Txt5 and finally
Txt6.

I need to tab in the follwing sequence:

Txt1
F1 Txt2,Txt3
F2 Txt4,Txt5
Txt6


All efforts to tab from Txt1 to Txt6 have failed (using TabIndex in the
Properties Window or VBA to set TabIndex)!.

Any help gratefully appreciated.

Thanks in advance.
