Question

ok, so this is in ActionScript 3, my problem is here:

var numCols:uint = 7;
numRows:uint = 7;

row = 1;
column = 3;

total = row+column-1    
for(i = 0; i < numRows; i++){
    for(j = 0; j < numCols; j++){
        if(j < column){
            array[i][j]=total--
        }else{
            array[i][j]=total++                     
        }
    }
}

I am expecting this result in array:

3,2,1,2,3,4....

However I get this:

3,2,1,0,1,2,3,4...

Answer 1

Problem

Your condition

if (j < column)

evaluates to true three times.

1. column = 3, j = 0, total = 3, total becomes 2
2. column = 3, j = 1, total = 2, total becomes 1
3. column = 3, j = 2, total = 1, total becomes 0

the fourth time, the else clause gets executed but by this time, your total has dropped to 0.

4. column = 3, j = 3, total = 0, total becomes 1.

Possible solution

I don’t know your use case but changing

array[i][j]=total++   

to

array[i][j]=++total

could be all it takes.
