Calling Global value in a subroutine

I have a subroutine script that requires a value from the master.

The master has a global specifier and is tied to a separate variable which obtains the value.

Ie.

global ObsNum
ObsNum = ObsArrayRow

The assumed global variable ObsNum returns the correct value in the workspace of the Master script.

The subroutine script then opens and continues executing and where I have stipulated:

n = ObsNum

The following error is thrown in the workspace:

"Undefined function or variable 'ObsNum'.

Error in AffineTransformationV1_0 (line 81) n = ObsNum

Error in Report3MainV1_0 (line 811) AffineTransformationV1_0() "

Do I need to do anything more to call the global variable ObsNum?

You have to use global ObsNum inside your function also. You declare the global variable inside the function.
