The easier you make it to read and copy your code the more likely it is that you will get help

Please follow the advice given in the link below when posting code , use code tags and post the code here

If you get errors when compiling please copy them from the IDE using the "Copy error messages" button and paste the clipboard here in code tags

You seem to be trying to use Mix both as a variable name and a function name

Change one or both of them to make them different

@fredicha, your topic has been moved to a more suitable location on the forum.

Please use code tags when posting code (see link in post #2).

Your sketch had a bunch of typing errors. Many '{' and '}' were reversed. I have fixed the errors and switched your command parsing from a bunch of 'if' statements to the "switch/case" statement designed to make that easier. It compiles without error or warning for me. Maybe it will do what you want.
