Yes, it is the correct list.

There is a more recent version (2.6) but that's unlikely to be the issue here.

Where are you defining this?

This means that the variable cannot be resolved.

Syntax looks OK.
There are two aspects to this:
1) is the variable being set up correctly and in time?
2) is the sampler set up correctly to use the variable?
I would start by disabling reading from the external file.
Define the ID variable as a fixed value on the Test Plan, and make
sure the sampler works with the fixed value.
Change the value and check it still works.
Then try to read the variable from the file; use the Debug Sampler to
show what variables are being set up.
