Two ways to do this. First way:

if (something)
     #do a bunch of stuff
     if (somethingelse)
         #do more stuff
     end
end

If you can't just nest them for one reason or another, here is  
another way:

firstif
if (something)
     #do a bunch of stuff
     firstif = true
end

if (somethingelse && firstif)
    # the above always fails since the second if doesn't see firstif)
    #do other stuff that is dependent on the first bunch of stuff
    firstif = false
end

Notice that mentioning the variable outside of the scope makes it  
available to both ifs.
