remove duplicates and sort array

[PeejAvery]

For example, in the code above when you alert(TestArray[2]); it only alerts one row of the array. And shouldn't it pick out the value SY400? It is alreting the entire row.
unique only seems to be returning 1 row. Can't figure out where though

What are you talking about? The code I posted only removes duplicates from one array. I have stated this many times. There is nothing strange about how it is working.

Sometimes, I need to check column 1 and remove duplicates leaving me with:
1,Jones, SY300
2,SMith, SY300

Sometimes, I need to check column 3 and remove duplicates leaving me with:
1,ABAB, Sy400

The above quote implies that you were just going to call it on certain arrays in the second dimension, NOT ALL. If you want it to remove the duplicates in EVERY second dimension array, you have to loop (for) through the first dimension while calling it upon the second.
