How to Reconfigure a Current Sense Amplifier Pspice Model
The error seems to indicate that the syntax given is not supported for F and H devices. By that it most likely means the syntax

F??? A B VALUE={expression} 
H??? A B VALUE={expression}

This doesn't really matter though, because these statements would have been equivalent to G and E statements if they were implemented:

So just swap the F and H sources by G and E sources respectively (just the first character would be sufficient), and it should give you the same results.

Disclaimer: I don't have access to PSpice myself so I can't test it for you.
