Need help creating a function for this picture

So, below I have a picture. My bot needs to click the runes in order from left to right and down. Once it clicks the rune it will sell it or keep it, if it keeps it then I want it to proceed to the next box; however if it sells it then it needs to click the same box it did prior in order to not skip.



rune1Row1 = Location (920, 615)
rune2Row1 = Location (1045, 615)
rune3Row1 = Location (1175, 615)
rune4Row1 = Location (1300, 615)
rune5Row1 = Location (1425, 615)
rune6Row1 = Location (1550, 615)
rune1Row2 = Location (920, 740)
rune2Row2 = Location (1045, 740)
rune3Row2 = Location (1175, 740)
rune4Row2 = Location (1300, 740)
rune5Row2 = Location (1425, 740)
rune6Row2 = Location (1550, 740)
rune1Row3 = Location (920, 865)
rune2Row3 = Location (1045, 865)
rune3Row3 = Location (1175, 865)
rune4Row3 = Location (1300, 865)
rune5Row3 = Location (1425, 865)
rune6Row3 = Location (1550, 865)
rune1Row4 = Location (920, 995)
rune2Row4 = Location (1045, 995)
rune3Row4 = Location (1175, 995)
rune4Row4 = Location (1300, 995)
rune5Row4 = Location (1425, 995)
rune6Row4 = Location (1550, 995)
I've got a function, but it feels very inefficient. I've got 24 lines in the function (1 for each of these locations) I feel like I could setup a loop that does something with the numbers in the variables.

Like clickSpot = "rune"..(something).."Row"..(something)

Anyone got any ideas how I can set a loop up for the variables here?

Edit 1: This is what I have for it so far

function runeSpotter ()
   if runeSoldHid == 1 then
       runeX = runeX - 1
       runeSoldHid = 0
   end
   if runeX > 5 then runeX = 1 and runeY == runeY+1
   end
   if runeY > 4 then runeY = 1
   end
   runeSpot = "rune" .. runeX .. "Row".. runeY
   runeX = runeX+1
end
