VBA - Copy Paste value base on the header - vba

Question

Hello Friends & Community, I am trying to copy and paste value from one sheet to another base on the header.
For example I have Sheet1 with Table as below
20200101
20200102
20200103
123
234
234
333
233
232
And Sheet2 with Table as below
20200102
20200101
20200103
I would like my vba code to copy & paste the value from sheet1 to sheet 2 using header as reference.
Luckily I was able to find below code that execute exact operation as I wanted. But the only issue is that the header from original source(Sheet1)doesn't start at A1(row 1 column 1) as the syntax desired. Also the paste destination header doesnt start at A1 either. I tried to alter several parameter in below code but never able to get it work. If anyone can help me understand below syntax and instruct me on which parameter I need to change in order to paste correctly it will be greatly appreciated. Thank yoU!
