Works for me. By the way, you don't need all these empty strings - this 
works too:

   local execute = keypress[1]..keypress[2]..keypress[3]..
     keypress[4]..keypress[5]..keypress[6]..keypress[7]..keypress[8]..
     keypress[9]..keypress[10]

And if you want to save some typing, or handle variable-sized lists, a 
shorter version is

   local execute = table.concat(keypress)

(see http://www.lua.org/manual/5.0/manual.html#5.4 )

That suggests that there is something wrong with what comes before the 
"if" - Lua is not expecting an "if" there, but something that completes 
whatever comes before.
