You defined V.in:=5V as a variable, but later use V.in as a function by writing V.in(t).

Thats the reason for the error message.

You have to decide, if V.in should be constant 5V or if it should depend on time!

Of course you can have both by defining V.in(t):=5 V   🙂

If Vin is not DC but Vin(t) you should do convolution.
