I've been trying to get Paul Spee's weather module to display today's weather info on my Home screen. I am a complete newbie when it comes to ProntoScript, but I have learned a few tricks, albiet quite basic. With the help of individuals from this forum it is now functioning properly. Thanks guys.

I've modeled my Home/Splash screen after the HTC Hero phone. The clock is working beautifully and I have the graphics pretty much complete. You can go to the full 5-day forecast (located in a different activity) by pressing on the weather icon area.

My Home/Splash Screen


Note: I've remove some comments and the copyright info here to shorten the post.

Note: I've edited the scipts below to reflect the current working version. The OnWake() function is working now. This function will refresh the weather data whenever the remote wakes up. There may be a more elegant way to write this... but it works. Also, you may have noticed I am starting to make some new weather icons.
