|I'm a tad confused.|
Are you saying that the master list is missing some of serial numbers that can be found on the other 10 sheets or that all of the numbers are there but the data is not?
In any case, before we could offer any specific code, you'll need to provide some details, such as the layout of the sheets.
e.g. What column are the serial numbers in? Is it the same on every sheet, including the master? Does transfer the data mean copy the entire row or a specific range.
The more detail you provide about the layout of the sheet, the easier it is for us to provide a solution.
