# For Loop

I am trying to make a grid (6 columns) as I duplicate layers, when I reach copy 7 it is positioned below the first ones. I achieved it with an if else expression but it is manual, I have to replicate the statement every 6 layers for it to repeat. "number" I added with the index of the layer.

basically I have the loop in javascript but I don't know how to integrate it to the Y axis position, I want the first row 1 (layer 1 to 6) to be at 5 pixels, row 2 (layer 7 to 12) to be 10 px and so on

"Math.ceil(number/6)" should give you the row number (starting with 1).

Hence, you want something like

5 + 5 * Math.ceil(number/6)

I'm not sure this formula is exactly right for your situation, but it should get you close:

``````numCols = 6;
n = index - 1;
col = n%numCols;
row = Math.floor(n/numCols);
x = 10 + col*5;
y = (row+1)*5;
[x,y]``````
