MS Calendar help requested: default to 1st of prior month

[timh2ofall]

Using Calendar in a 97 UserForm to enter dates into a textbox. I want
it to default to the 1st of the previous month on opening.
I tried using the month property set to 0 and then using PreviousMonth
as the Sub but suspect that it won't change after the next month comes
around.
Made a feeble attempt at trying Today -30 just to get to any date last
month.
Any suggestions?
Thanks!
Tim
