plzz explain me the concept of comma in i/p & result hw floating pint variable accepts "," and not "." in result msg box

[@jeffschultz4168]

I'm using 2015 and this does not happen to me, in fact, it parses out commas. This did not make any sense to me, perhaps it is something else such as formatting of the text boxes that is causing this.

[@kwstasber9190]

Perfect
