increasing the row number using JavaScript?

I'm trying to increase the row each time around the loop, but it's not increasing is there something wrong with my JavaScript code?

var image= [];        
for (var i = 0; i < test.length; i++) {
    var avatar = test[i].image; // The profile image
    var row =5;

    if(i % 2 === 0){
        image[i]= Titanium.UI.createImageView({
            top:row,
            image:avatar
            });
        win.add(image[i]);
        //trying to increase the image
        row =row+200;
    } else if(i % 2 === 1) {
        image[i]= Titanium.UI.createImageView({
            top:row,
            image:avatar
            });
        win.add(image[i]);

    }
}

You are initializing row in each start of loop. Try taking your var row = 5 outside of the loop:

var image= [];     
var row =5;   
for (var i = 0; i < test.length; i++) {
    var avatar = test[i].image; // The profile image

    ...
}

try to move this line upper outside of the loop :

var image= [];        
var row =5;

for (var i = 0; i < test.length; i++) {
...
}

Can't say I'm certain of what you're attempting to achieve, but at the beginning of your for iteration you're resting row to 5. You should move your var row=5; declaration to the top with var image[];

You might also consider the short form row+=200;
