Challenge 9 - Help! Same code but cant use


#1

Previously, in challenge 7,8, I am using about the same coding and said “congratulation” but now it keep mentioning “Your code ran but did not produce the correct result.” I have little programming background, but I really cant figure out where did I did wrong

function lightCell(coordinate)
{
return GRID[coordinate.charCodeAt(1)-49][convertColumn(coordinate)];
}

function isShip(coordinate)
{
if (lightCell(coordinate) === “v”) return true;
else return false;
}


#2

Looks to me like the same problem explained here:
