I would appreciate any assistance for a macro that helps out with the following command:

Find a cell that contains AB-123 within it, once it finds that cell then automatically go down 1 row and insert two blank rows.
If possible, I would like this macro to keep looping itself until there are no more rows of data to search thru; however if this looping can't be done that is no problem because i can find another way of repeating this process manually.
Thanks for any help.
