I am wondering how to declare a global variable in appery. I am making a list of check boxes, and when checked I want to set a boolean variable to true for each box. I want to be able to give messages in the RSS feed tags, and I want the RSS feed to only show messages for which the user has the tags checked.
Basically, I want the checkbox to set a boolean for it's corresponding tag to true. Then I want the RSS feed to display all content with tags that the user has set to true.
How might I go about doing this?
