Yes, the command is nextlevel=X, from the manual

Nextlevel=X
o Makes it so when the current level is completed, Level X will begin."
Quote: "does that mean that variables from previous levels are not carried over"
From my experience, yes they do carry over.

I'm not sure,but it is very easy to make.
:state=0:dimvar=money,setvar=money 100
:state=0:hudreset,hudx=24,hudy=4,hudtext=Money,hudsize=20,hudname=money,hudmake=display
:state=0:hudreset,hudx=23,hudy=8,hudsizex=16,hudsizey=16,hudimage=gamecore\huds\numeric1.dds,hudname=moneyhud,hudtype=6,huduservar=money,hudmake=numeric,state=1
This was my setup to display the money, then all you need for purchase is to add, vargreater=money X, to the script.
Hope This Helps
