Saving a total in the footer

I made a textbox in the footer to capture the total for my inputs into the blank fields...but it seems to only update when I click to save the form.  Is there any coding I can write to save (update the footer field) when I input into the blank field in the detail section?

is the textbox in the footer bound to a field?

if not, place this in the control source of the textbox

=nz(text1) + nz(text2) + nz(text3)

replace name of textbox accordingly
