Increase/decrease values in a field using a "+" or "-" button
Operating system version
Mac OS 10.6.5
Description of the issue
I would like to use buttons to increase or decrease values in a field; I have found this: http://help.filemaker.com/app/answers/detail/a_id/4709/kw/increase%20value%20by%20one that works fine only if the starting values is not 0 (zero). I am planning a database to report the score of basketball game: all the players values are set at "0" at the beginning of the game and the first increase must be from 0 (zero) to 1 (one).
