Python Dbuttons error TONGUE.py

hi thomas,
here i attached my code for creating auto rotate setup with expressions but if i use directly this code run working fine but if im using Dbuttons its showing error in callable so can you point out what callable mistakes

Probably getting an error because of this:

dButtons={'Run': 'tongueWaveExpression'}

the values of that dictionary need to be functions

But why are you creating a button for that? You just need simple function, right?

thank you , im trying to create multiple buttons for multiple choice setup to check more implementation in futures so digging
