I've tried using the Concat and ++ functions, but to no avail so far.

Imagine the strings are set out in a 9x9 grid type way, and i have to find
the value of a set position given 2 gird values.

> getCharFromGrid (row,col) g = concat g !!(row * 9) + col

The decleration is

> getCharFromGrid :: Position -> Grid -> Char

Any ideas why its not working?
