(Assuming the script only works at set locations)The best place to get this answered would be on the script thread itself.
If it's an AIO script, then you can just google up good training places on runescape, there are tons of great guides and fansites out there, another good place to check would be the thread of ANY fighting script at ANY bot-site, so you can just get the info and input it into tfighter.
Also you didn't give us your stats, so we cant possibly suggest you any specific areas without that information.
If the script isn't functioning properly, it's best to submit a detailed report of the issue on the script's thread, that way the developer can work on fixing the issue.
