What do you want to happen if the textbox is empty or Null when the button is clicked?

And if the textbox is at 0 (zero) when the button is clicked, do you want to go into negative numbers?

the textbox will not be null at least i would have no reason for it to be... it would just be at 0 and yeah negative numbers would be good... thanks

As you share no details I will have to invent names for you. You can update it to match your own names I expect :
Expand|Select|Wrap|Line Numbers
  1. Private Sub cmdSubtract
  2.     Me.ATextBox = Nz(Me.ATextBox, 0) - 1
  3. End Sub
