[SOLVED] Hey! Having trouble with using "i" and variable names. Got error: "Reference error: Can't find variable: layer"

You must put all the variables in an array to occupy them.

Mike Johnson

When using the bracket syntax [] you are effectively calling properties on the object before them. So layer["i"] is the same as writing layer.i

Since layer does not exist, layer.i will throw an error. Putting them in an array works. If they are children of another layer like listItems you can use listItems.children as the array.

you probably could write it like this too:

window["layer#{i+1}"].width = initialWidth
