ToWP: $(var) or $var

| WebCab.de | ToWP | Next |

The WML specification defines $(var) and $var as legal variable names. If there is any unallowed character directly behind the variable name $var then a WAP browser may pop-up an error message. This can be avoided with the brackets around the variable name: $(var) because this clearly defines the variable name inside the brackets.

NO:

Your choice was $color!

YES:

Your choice was $(color)!
