put the bracket beside the variable.

ok, so try orcad parameter sweep,


keep on pop up error,
**** INCLUDING SCHEMATIC1.net ****
* source RESISTORS
R_RS N02282 VL 47k TC=0,0
V_V1 N02282 0 10V
R_R1 0 VL rvariable TC=0,0
-----------------------------$
ERROR(ORPSIM-16152): Invalid number
.PARAM rvariable=10k

**** RESUMING "global sweep.cir" ****
.END

at the end is because i did not put the bracket beside the rvariable which is supposed to be parameter.

hehe, so stupid...
