Hello experts,
Sorry I didn't explain it clearly before.
Actually the lower case action in the function definition was uploaded by text file(not manually input). And now every time I open this function in NWBC and try to save, it will show the "duplicate action" error message. So I have to remove either lower case one or upper case one, and save again. After the save, the deleted one will just come back.. And next time I open this function, I have to remove it again.. It's very annoying...
