[Tutor] Fw: path string

[anatta anatta]

Dear Tutor,

Please disregard my request below.

I know the problem!

I have not defined the variable in question as a global variable.


regret the inconvenience caused.


Best.

Subject: path string

Dear Tutor.

I am trying to create unsuccessfully source path as a string 'str7' in part_1 of the code below, to be used in part_2 of the code.
When I define the source path explicitly in part_2 of the code (#sourcePath = r'H://TCVFLDAT'), the code works right.
How else could I find the path in part-1 and use it in part 2?
