I have this working with one starting form, and I have
the conversion form passing the data back by explictly
identifying the text box it came from.  But I want to
call this conversion form from many forms, so I have
tried pasing the name of the form that called the
conversion form, but I cannot seem to use this string in
the command to put the focus back to the orignal form and
text box.  Is there away of using a variable name
for "CallingForm" and textbox1" in a lines like:

' this is unloading conversion form and tring to get back
to the calling form...
Private Sub Form_Unload(Cancel As Integer)
'set focus to textbox that called
CallingForm.textBox1.SetFocus
'paste new value in textbox that called
CallingForm.textBox1 = NewValue
end sub

Thanks
Ted

Private mCallerTextBox as TextBox

Public DoConversion(txtbox as TextBox)
    set mCallertextBox = txtbox

:
:
Form_unload()
    mCallertextBox = "New Value"
    mCallertextBox .setfocus
    set mCallertextBox  = nothing
