Modeling CSP using S-CO2 as HTF in SAM 2015.6.30

Hello,
I am using SAM to model a CSP Power Tower using S-CO2 as the HTF and comparing it to the CSP power tower molten salt in order to prove the high system efficiency and low LCOE in using S-CO2 as the HTF. However, when simulating the model for the S-CO2 CSP, I am getting the following error:

"ssc variable does not exist: 'HTF'
Simulation tcsmolten_salt failed.
SSC requires input 'gen', but was not found in the SAM UI or from previous simulations
Simulation singleowner failed."

Any ideas on how to fix this error?
Any advice with how to go about this project will also be greatly appreciated.

Thank you,
Ethiopia
