thanks for that Mangesh but I now get a runtime error 13 type mismatch, I
dint suppose you can help with that, I am using numbers I guess it is
looking
for a text or something. Any advice would be great - Thanks

In your user_form, double click on the textbox tb1, this will open the
VBE
with the following:

Private Sub tb1_Change()
tb3 = tb2 - tb1
End Sub

Repeat for the second textbox.

In the change event for the first two textboxes, put the formula:

tb3 = tb2 - tb1

I think this is a simple operation but I can not find the way to
do
it.
I have a excel user form with 3 text boxes, tb1, tb2 and tb3. I
want
to
use
tb3 to show the results of the enteries made in tb1 & 2. For
example
tb1 = Maximum
tb2 = Minimum
tb3 = Maximum - Minimum
After the entry is made in tb2 then tb3 will automatically show
the
calculated result as the user will not be allowed to move onto
that
textbox.
At this point the record wil is part of a larger form and not
updated
to
the
worksheet.
