Removing fill colors from shapes?

[southwestform]

I drew some squares using shape layers and filled them with white and added a stroke using layer styles.

How can I remove the white fill color and make them transparent so they reveal the layer underneath?

Thanks.

Change the layer fill opacity to zero.

Doing this gets rid of the stroke I applied through Layer Styles. How can I keep a stroke around the shape?

Nevermind, I changed the opacity and not the fill. That took care of it.
