I keep getting a expected then error when I have the the in the string - computercraft

Question

I keep getting the then expected error on line 61 and I cant find the problem any ideas?
I tried working it out and rearranging it im using computer craft periherals mag card reader and trying to mag a card door

You miss spelled "modem" with moden on 2 lines.
if moden == nil then
and also..
if moden.isPresentRemote("mag card reader_0") then
As for the error.
if SHA,SHA1_2(p1) == cards[x] then --line 61 is right here
i believe.. should be this..
if SHA.SHA1_2(p1) == cards[x] then --line 61 is right here
swapping the , for a . should do the trick.
