Re: globals

Global variables are only available in other scripts if the other scripts are included into the script where the variable exists. To help understand this concept, remember that every file you include is inserted inline into the main script file before it is executed. You end up with one long script before the code is actually executed; so if you have a global variable in one, it will be available in all the others too. Hope this helps.
