I have several hundred lines of code that look like:

Sheets("First").Select
[LOTS OF CODE HERE]
End of code

If I want to repeat all of the same steps on two other sheets, do I have to
copy and paste the code twice under the names of the two different sheets or
is there a command I can use to repeat all of the code on different sheets?

Thanks

(P.S. I am a total novice, so the easier the solution the better.)
