No, it won't work, because you move it up to 50, then drop it back by one, 
but you don't consistently go back by one.

I'm not sure exactly what you're doing with this (having gradually shaded 
sprites?) but consider starting with something like this:

-- Init timex (these are globals or properties) - init somewhere
timex =1
direction =1
maxTimex =50
minTimex =1

on updateTimeX
   timex =timeX + direction
   if (timeX = maxTimeX or timeX = minTimeX) then
      -- Must reverse direction for next time, multiply by -1 to flip direction
      direction =direction * -1
   end if

   -- Now do whatever you want to do with timeX
   -- Modify your sprites or whatever
end
