Help~Could I set the value of a part as 2times of another

[tongtongsd]

Hi guys:
I am doing some parameter sweep simulation on PSPICE student version9.1

I set up a value of capacitor 'Cc' as a parameter (in PSPICE part "{c1}")

and Could I set the value of capacitor 'Ca' as '2*{c1}' , which means 2 times big as it of another 1?

It failed to run the simulation and I am wondering is it possible for this function? and how could make happen.

Any help will be so appreciated!~!!~~

Following is my shematic:

I haven't used pspice in many years but if I remember correctly you need to write '{2*c1}'

I hope it helps!
