Error: at least one equation must be declared

We are simulating a simplified DSGE model with endogenous innovation.
And we are getting the error “at least one equation must be declared”. We tried to fix the issue, but couldn’t find a solution. You can find our code attached. Thanks in advance.

There is a problem with the encoding of the file. It contains things like
\fs20 \fs24 \

Thank you Mr Pfeifer,
we have solved this problem. However, we cannot find the steady state now.
Can you help us with this issue? That would be much appreciated.

You need to provide proper initial values in an initval-block as several variables cannot be 0 in steady state.
