If not exists, return false

Hello, I'm kinda stuck on this piece but can't get it to work unfortantly.

function checkHBMChances()

   toast("Gonna check our chances")

   all = findAll("hbmChance.png")

   count = table.getn(all)

   if(hbmchance_reg:exists("hbmChance.png")) then

       if (count > 1) then

           toast("We have " .. count .." chances")

           return true

       else

           return false

       end

   end

end
Edit : fixed

function checkHBMChances()

   toast("Gonna check our chances")

   all = findAllNoFindException("hbmChance.png")

   count = table.getn(all)



   if not (hbmchance_reg:exists("hbmChance.png")) then

       toast("We don't have any chance(s)")

   else

       if(hbmchance_reg:exists("hbmChance.png")) then

           if (count > 0) then

               toast("We have " .. count .." chances")

               return true

           end

       end

   end

end

It does return true, with the amount of chances.

if (hbmchallanges_reg:exists("HBMChallangeScreen.png")) then

toast("We are in the HBM screen, gonna start the chosen HBM")

if (checkHBMChances() == true) then

toast("Can do some sweepes mate")

selectedHBM()

sweepHBM()

end

end

Because it continues to sweep()



It just wont return false if it can't find the image, instead it throws me the error. 

The image that it has to find



Hopefully someone can help me out.

Edit : fixed it.
