Please format your code using the {} Code block and give enough information for people to understand what you are asking and what your inputs and functions are.

The error in the question title suggests you are calling a function, but unless AWG is a function I don't see one. If AWG is a function then you are calling it with no arguments.

Whilst that is valid syntax (for calling a function with no arguments) I personally prefer to always use '()' for a function call even with no arguments.
