I was
going to try to reply to your question, but I wasn't sure what you
meant, so I need some more information. I have tried to ask my
clarifications in specific below:

<I have a need to design  a function  that enables the user  to go back
into the form> . . . as in click on a button? . . . select it from
a custom menu? . . . as an automatic response when you do something
like click on a worksheet or change a value in a cell or . . . ?

<utilize a password  field (already built)> so, I'm assuming you
don't need further help with this part

<enter searchdata (from the datadump excel  sheet-like a ticket
number)> as in, enter  criteria that the search, or filter, is based
on? . . . like "all the listings from "Jan 1 to Jan 30, 2008" ? is
that what you meant?

<and have the userfrom be re-populated with the initial data.> I'm
thinking here that you mean to have the userform be re-populated
with that filter or search  criteria in place, so only those items
which match are listed . . . is that what you meant?

And, by the way, I don't know what being "relatively new to VBA"
means, actually . . . but, compared to someone who has used it for
decades, I'm new, too.

Welcome to the "not so silent" part of this great group, though.
Honestly, no one has been shot for saying something yet, although
I'm sure they were tempted to shoot me on occasion.
(Still, they meant well, even as they aimed.)

Have a great evening/day,
