Cleaning Up Regions

I am working on trying to optimize my code better by using Regions.  I stated by setting a region to the variable r then call my click command with r:.  Then I ran into an issue that I need to use an if-else statement which I did not know of a way to set r before the next else.  Then I started to have to make separate variables for to store each region.  
Is there there a cleaner way to setup variables for regions?  I am thinking I should set them all at the beginning and not try to worry about setting them when I need them in the logic.  Or just using the hardcoded region instead of a variable.



   r=Region(60, 963, 150, 150)

   rQueueMax=Region(60, 963, 150, 150)

   rMaxLimitOK=Region(285, 450, 150, 150)

   rOccupy=Region(410, 502, 150, 150)

   --r:waitClick("QueueMax.png")

   if (existsClick("Attack.png",5)) then

       waitVanish("Attack.png")

       if (rQueueMax:existsClick("QueueMax.png",5)) then

           r=Region(449, 965, 150, 150)

           r:waitClick("March.png")

           r:waitVanish("March.png")

       elseif (rMaxLimitOK:existsClick("MaxLimitOK.png")) then

           rMaxLimitOK:waitVanish("MaxLimitOK.png")

           r=Region(583, 119, 150, 150)

           r:waitClick("AttackCancel.png")

           r:waitVanish("AttackCancel.png")

           r=Region(-33, -40, 150, 150)

           r:waitClick("EmpireCenter.png")

           return

       end

   elseif (rOccupy:exists("Occupy.png")) then -- Farm not in location, skip: Flag to not attack again?

       r= Region(554, 285, 150, 150)

       r:waitClick("AttackCancel.png",3)

       r:waitVanish("AttackCancel.png")

   end
