Undefined variable is simple
Define the empty scenario as required to patch the error however that wont fix it seeing that error above you posted, since i dont run those versions nor can i test those versions im afraid you'll do the work to figure it out its a default script from Tbdev so get it from there RAR, and i havint touched it so i aint fixing someones screw up cos i do enough of that on a daily basis, its no secret that i dont actively support the previous versions because active support is reserved for the latest V rev only which atm is V2 which has months left because im about to release a new version. Feel free to post it in my own support forum where you have the chance of someone helping you no matter the version, anywhere else your simply wasting your time.
