Error message

I am in trying to use PML in a learning exercise, I keep getting this error message:

Error line 8: Expected: ‘)’
C = A1/V
^
Error line 25: Error: Assignment only allowed at top level
fixef(tvCl = c(, 12, ))
^

Any ideas on how to solve the problem?

The lines that you show do not contain any syntax errors. It expects a close parentheses in a preceding line.

Can you provide the full PML code to diagnose the issue?
