here is the important hint. the (tcl) code that is about to be
executed starts with tclForcesScript this should not be.

this is your mistake. never copy stuff without thinking.

you have not read the documentation well enough. the example shows
the "{script}" variant, but you are using the "file" variant.

what you are calling is effectively:
tclForcesScript tclForcesScript { ... }

which cannot work and explains the error message.
please re-read the docs and edit your script file
accordingly.
