Hi folks
We have inherited a set of files for operating a library self-scan machine. The javascript function for printing a receipt works fine in IE, but does not print anything when run from Firefox. We need it to be FF-compatible. We don't know a thing about javascript.
I thought perhaps some of the fine intelligent folk here on the forums might offer to cast an eye and let us know if they can spot what's not FF compatible? As we don't really know enough to know which bits of what files are relevant I'd rather not just post it here as I don't know which parts are going to be useful to post. But if someone has the time and inclination to help, I can send you a few files for review. Let me know your email if you're keen.
Thanks very much
