output module "Full Flat Path" not working as expected

Hello,

My script contains this line:

var new_dataMOVIE = {"Output File Info": {"Full Flat Path": fullFlatPathMOVIE + myCompText}};

The path it creates is correct, but when AE makes the output module it's adding a duplicate volume and subdirectory to the beginning of the path.

For example, the script builds a path that reads:

"/Volumes/ourserver/PROJECTS/ourproject/user/shot/...etc"

Which is what the actual path should be.

But after it adds the output module, the output module path now reads:

"/Volumes/PROJECTS/Volumes/ourserver/PROJECTS/ourproject/user/shot...etc"

Am I using "Full Flat Path" incorrectly?

Thanks, all, for any help.
