Does tickertag give you 2 different options for the tickers? I have created tickers from 2 other sites (tickerfactory and ***************) and on both places, they gave me multiple "codes" that I could use. I just looked at my signature and I used the option that started [url. My suggestion is to go back to tickertag and see if they also give you the "codes" for an option with url near the beginning.
Good luck!
