Both errors directly follow references to "R4", which seems is not a coincidence...

Perhaps you need to specify the field specifier of A, as in:

D1=A A

Almost correct, but the required field is W, not A. Change every R4=C to R4=C W and change every A=R4 to A=R4 W and so on. When the W field is the only one valid for a command, the syntax should allow it to be omitted, but apparently in this case you have to specify it. Silly assembler! Sad

Two lessons learned here: (1) When the error message is "Invalid Field", look for a bad or missing field specifier. (2) Very often the error pointer will be pointing at the line after where the error actually happened.

Hope that helps!
