Command button to search and replace value in table

[Electech99]

Hello, I'm trying to build a document to update serial numbers in a table that has around 1000 total entries.
I've created the table and the drop lists to load the information for the current serial number and that works as it should.

I've created the button and tried using google to get it programmed for a search and replace function but it keeps giving me an error, no matter how I input the values.
The table and the button are on different sheets.
Can someone please tell me what I'm doing wrong?
