Pull content from 2 xlsx files into a master xlsm file under a single MACRO button

I have a macro button in ABC.xlsx that would open up another excel file 123.xlsx, copies the content and paste it into a sheet in ABC.xlsx.

This one works no problem. But I'm having trouble to code under the same button to open up ANOTHER xlsx 456.xlsx to copy its content and paste it in another sheet in ABC.xlsx.

I get this error when I try to run.

Compile error: Duplicate declaration in current page. highlighting "wb As Workbook" as bolded below in my code.


What does this error mean and what should my code be like in order to pull info from 123.xlsx paste in a sheet in ABC.xlsx, then pulls info from 456.xlsx and paste it into another sheet in ABC.xlsx, all under the single button?

Please advise.

Here is that part of my code:

NOTE: Cell G2 contains the path on the harddisk to find 123.xlsx. G1 contains path on hdd to find 456.xlsx.
