Problem with running NAMD config file

I'm a new a NAMD user and I'm trying to equilibrate a lipoprotein system
via a simple minimization and equilibration simulation. I've written the
required NAMD config file using the NAMD tutorials but when I try running
it I get the following error message:

FATAL ERROR: tried before startup to read config file parameter that was
not set
    while executing
    (file "CSApoA1.conf" line 30)

I don't understand what the issue is. I've checked online to resolve the
issue and found that the .prm extension are for the parameter files so
there shouldn't be a problem with providing the correct parameter files.
Therefore I'm confused why I'm getting this error message because I got
these files from the provided plugin tcl folder.

I would be very glad for your help.
