Recurrent error

in RIOS
Hello!
When running the program, an error pops out.
I´ve been trying to workaround the problem, but I think it is time to ask for help. The error is "TypeError: float() argument must be a string or a number"
I´m attaching some information. If you need something else, I will gladly answer to your request.
Thank you so mucho for your time.
