A device may appear in .DC and .STEP commands only once

Iam trying to perform DC Parametric Sweep Analysis on a simple circuit
having netlist

**** INCLUDING parametric2-SCHEMATIC1.net ****
* source PARAMETRIC2
R_R1 N00047 0 {Rval}
V_V1 N00047 0 10Vdc
..PARAM Rval=1k

I changed the value of resistance to {Rval}, placed PARAM and edited
it, placed a new column named Rval with initial value of 1k, all in
the same manner as mentioned on Pspice User's Guide Page No. 85. In
simulation settings I selected global parameter and named it Rval,
with start value of 1k , end value of 10k and increment of 100. Now
when I simulate the circuit I get error "A device may appear in .DC
and .STEP commands only once". What is the problem?

Thanks

You probably have declared the same PARAM in both "DC Sweep" and
"Parametric".

Post your *complete* .OUT file for a more thorough analysis.

You're probably also using Capture... I feel so sorry for you :-(

Thanks for your suggestion it immediately solved my problem. Is there
some problem with Capture ?
