ok..there are known issues at the switch side on using special characters like "|" etc in the banner text.
In case you would really like to use, say "|" in the text, make sure it is enclosed in quotes in the banner text. That should avoid this problem
ps : thought will remind of this important etiquette followed in the forum - assign points on scale (1-10) to people trying to help by answering your queries; its an appreciation for the time they spend in responding to your questions.
