[Staffslug] Javascript Problem

Hi, Would it be ok to submit a javascript problem?. I simply cannot figure out why a function exits and is called again from somewhere but I am stumped as to how it happens. I am not a programmer but I have done quite a bit of scripting. I have tried in all major browser and the problem occurs in all of them. I'll post the whole script, html - css and javascript with a description of the problem if one of you clever guys wouldn't mind have a quick look. Very many thanks, Walter
