Ticker factory-update to weight and exercise ticker

I know some of you are very savy with web pages, so I'm hoping for a little instruction on using tickerfactory.com code to update my tickers. I've tried updating the code directly in Weigh In site in edit mode, but it doesn't stick. Please help! I like to have fun and learn something new at the same time - and this would be a lot of fun. thanks much in advance, tammy
