Help is here! LOL!
Can you do me a favor, and email your siggy code to me (PM would work too). I would have you post it here, but it will just reduplicate in the post, and not help either way. Once I have your code, I can tell you what to change.
Or, check out the "Helpful tips and tricks" post at the top; it's got not only a code in it that may be helpful, but it also has a great link that may help with your siggy.
Until I hear from you, I will keep working on it!
