"Unable to Load" in Notification Center

[Brando]

My program was running just fine yesterday, but after making slight changes, only changing and reducing the HTML calls, the program only runs from the console. The Notification Center says "unable to load."

As @JonB would say, "double check line 17. thats where your problem lies."

It's hard to say without seeing your code. It could be that the widget is running out of memory (it gets far less from the system than the main app), or that you've run into a bug. Certain modules/functions are not supported in the widget, but usually this should raise an exception instead of crashing. Again, without seeing your code, it's hard to tell.

Ok thanks, I'll share the code, I realized memory could be an issue. Just to let you know I took out the URLs because it has personal data on it.

Not sure why the one comment is huge but that is the code, I know it is not efficient and I haven't cleaned anything up yet. Thank you for the help.

Your code work well for me in the Today widget after a few minor changes:

• Create a URL variable that is still valid if a number is appended to it
• Use that URL in 3 places to replace ' '.
