Also, don't forget to name the MOSFET with the right model name.? On your schematic, you have defined a P-channel MOSFET model with the name "CMOSP":
.MODEL CMOSP PMOS ( ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?LEVEL ? = 49
Therefore, the name next to the PMOS symbol (M2) must be changed from "PMOS" to "CMOSP".? This is true for either the PMOS symbol or the PMOS4 symbol.

If you don't do that, you would end up simulating with the default SPICE MOSFET which is 50-year-old CMOS technology.
