Hi Tony,
In RTE Basic scripts you need to include the colon character at the end of the Include keyword, for example:
'$Include: "script1.bbs"
Yes, you can use the full or a relative path to the file. If no path is specified then the file needs to be in the Scripts Directory, which is usually <Documents>\BlueZone\Scripts, so any relative path would be off of this path. Does this work?
Thanks,
Mike
