Use the lost focusevent of the 4 input textboxes to write the sum to textbox five. Create a procedure (in a PRG) or a method on the form.

In each TextBox Lostfocus area enter this code:
AddTextBoxesToTotal(thisform)

procedure AddTextBoxesToTotal(oform)
with oform
.txtMyTextBox5.Value=(.txtMyTextBox1.Value+.txtMyTextBox2.Value;
                    +.txtMyTextBox3.Value+.txtMyTextBox4.Value)/4
endwith &&oform
endproc
