Use the substring function to remove the Text before / after a character index number.
Since I've already helped you once with listboxes and explained what you needed to know, I'll go ahead and give you another example of the functionality string manipulation.
I really hope you are learning something here, I've given you all the knowledge you need to do this on your own. I'm expecting this to be resolved, if you continue this thread with the same question in the OP I wont respond.
