syntax: change formname control reference in vba code.

I have two forms.
frmNew
frmUpdate

Both contain some of the same control information to create an e-mail message. (sender name / recipient / subject / body / etc.)  Both forms can be enabled at the same time (they're on different tabs of a multi-tab)

I have ONE module to create the e-mail object itself.

Depending on if the user clicks the "Create E-Mail" button on frmNew or frmUpdate, I want the module to gather the required information for the email from that specific form.

This is what I've been doing so far:

There is a public variable (integer) called TicketType
on the frmNew onclick event:
TicketType = 1
Call CreateEmail()

on the frmUpdate onlick event:
TicketType = 2
Call CreateEmail()

Then in the CreateEmail module/function I need it to reference the correct form / controls depending on TicketType.

I was thinking of:

If TicketType = 1
    then FormName = frmMain
else
   FormName = frmUpdate
end if

Then I could have one reference for controls such as "OutlookTo = FormName.txtAccountNumber.Value" and it would reference the correct form.  unfortunately this is not the correct way to reference form controls... so I need another way to do it.
