i feel like i might be going insane here-- am i getting the cameras wrong? i put in 7 4 1, and everything else is absolutely correct -- but it's still telling me i've got errors? i cannot figure it out --
two of your cameras are wrong! try figuring out what the other camera numbers are (the ones that the schutters did not appear on) and then using process of elimination and the clues in the descriptions to find the rest
