Does anyone know if I can dynamically specify a unique dataURL for a single HTML screen by the calling object? For example, I have a Menu List that's dynamically populated by items based on the users location. When clicked, I would like any one of those items to move to the HTML screen and load content from a URL specific to the parent list item. I suppose I could generate a custom HTML screen for EACH item in the list, but this seems messy or prone to memory issues. Thanks.

You could link the menu item to a php script that would dynamically create an HTML page on the fly based on parameters you send it...that would work! Mark

That's what I ended up doing. I had been trying to link to a pre-defined HTML screen with a custom dataURL for each path to it, but that failed. Ultimately, I just added the necessary JSON to create a new HTML screen for each list item when clicked. Thanks again.
