totally spice newbie...

hi.. im new to pspice software, currently exploring pspice student edition. im trying to simulate a list of code i found in a journal regarding thermoelectricity.

* SIMULATION OF MEASURING SYSTEM
* TAMB = AMBIENT TEMPERATURE
* SE = SEEBECK CONSTANT

.PARAM TAMB=296.4, SE=0.05292, RM=1.806, GND=0

*THERMAL CIRCUIT 

*HEAT SINK
VTAMB 3 0 DC {TAMB}
RKRAD 4 3 0.34
CRAD 4 0 340 IC={TAMB}
RSILH 4 1 0.143

*THERMAL PELTIER MODEL 
CH 1 0 2 IC={TAMB}
GPE 0 1 VALUE={I(VPOS)*(I(VPOS)*RM+SE*(V(l)-V(2)))}
RKM 1 2 1.768
GPX 2 1 VALUE={I(VPOS)*(SE*V(2)-0.9*I(VPOS))} 
CC 2 0 2 IC={TAMB}

*THERMAL MASS
RSILC 5 2 0.143
CCONINT 5 0 304 IC={TAMB}
RCONINT 5 3 3.1

*ELECTRICAL CIRCUIT 

*ELECTRICAL PELTIER MODEL
VPOS 11 13 DC 0
RM 13 12 1.8
EALPHA 12 0 VALUE={SE*(V(l)-V(2))}

* EXTERNAL CURRENT SOURCE 
IPOS 0 11 2.1

.OPTIONS RELTOL = 5U
.TRAN 1 2K UIC
.END

the code i run having these following problems:
ERROR -- Node l is undefined
ERROR -- Node l is floating

help needed... tq

I think it could be that in the line defining EALPHA you have V(l) instead of V(1) i.e. the letter 'l' instead of the number '1'.

hey Keith...

wat a silly mistake i have done... btw thanks very much for the tips....
