Part VIN has no 'STIMULUS' property

Ok. so today I run the PSpice, and face the problem
INFO(ORNET-1041): Writing PSpice Flat Netlist C:\Cadence\SPB_16.6\OpenAccess\resistors-PSpiceFiles\SCHEMATIC1\SCHEMATIC1.net
ERROR(ORNET-1110): Part VIN has no 'STIMULUS' property

constantly make the error, whether i change Vac, Vdc, but life is always like this, you never realize you make the mistake only after you make it.

Hehe. I have extra component in the bottom page, that's why i have that error.
once I remove the extra component of power source, the error disappear.

remember at the start, you create a project based on simple.obj.using the design template.at the corner you can see the following figure, remove it.

as it create extra power source, that's why your simulation is not running, once you remove, our circuit is completed and in a closed loop, so everything is working fine.

hope it helps.
