I have a string that looks like this: TA-TTC-TTD. How do I insert TB after TTC so that it looks like this after the insert:<BR>TA-TTC-TB-TTD. Remember the only things that's fixed is the dash after TA. Example the string could look like TTTA-TTTC-TTTD. But I would like to insert TB so that it looks like TTTA-TTTC-TB-TTTD. Didn't mean to repeat myself but wanted to get the point across.
