Fixing A Data Export Issue

Hi

I have a bit of a bizarre problem when exporting data out of a certain system. There is a known bug where sometimes it splits data, that should be on 1 line, across 2 lines. It's always done in the same way, and I'd like to write a macro to do the following:

- Search column B for "12"
- If it finds it, highlight the 11 cells next to it (including that cell), and cut it
- Find the next populated row up, move along to column L and paste it

I'm not sure I can do this all in one step, or if I need to move cell by cell. But any help on this would be fantastic.

Cheers.
