bios:388: [string "screen"]:48: syntax error

My brother and i are big fans of the PORTAL series and together we started recreating portal in minecraft (FTB Ultimate)
but since he is not good at LUA i am working on a simple program to make the "screens" in the chambers:
http://www.telnets.o...st_Chamber_Sign
But for a unknown reason i get an SYNTAX error:

(btw, i know that this is not the best way to make the program but i am making it simple so that my brother can learn with me)

The error is at line 48:

Can someone help me please?

Line 47: term.setCursorPos instead of term,setCursorPos ("." instead of ",")

that was a noob action
thanks LBPHAcker…
