[AccessD] Increment or replace?

Kath:

I need them to be able to either add to or replace the value.  This is a
continuous form, BTW.

Rocky - couldn't you assume the + sign as the default? Only subtract IF they
enter a minus sign?

  Dear List:
   
  I have a text box on a sub form bound to a numeric field which contains,
  obviously, a numeric quantity.  
   
  If the user inputs a value in this box preceded by a '+' or '-' sign, I
want
  to add or subtract the value entered from the current value.  If they
enter
  a value without a preceding sign, I want to replace old the value with the
  input value.  
   
  I can obviously see if they entered a minus sign because the number is
  negative.  But how can I know if they preceded the input value with a '+'?
