Just to finish this one off, I discovered my problem in IE6 was nothing to do with the jquery search operation we were discussing.
As I was working on the code I had added an object initialisation above the line in question that had an extra comma at the end, as in- var frames= { EM: 1*offset, . . . YH: 10*offset, //<<extra comma here }; IE6 choked on this, whereas Firefox was quite happy with it. I've done enough little bits of Perl, PHP, and now JavaScript over the years that I have terrible trouble remembering exactly which bits of syntax will or won't work with each! Thanks again to Jason, my little dynamic map works like a charm.
