Changing CSS z-index

[transmoderata]

Page in question: http://www.therabbitshome.com/


I thought this would work but it doesn't:

var t_3_l_1=document.getElementById("trhbg_t3_l1");
var t_3_l_1_zindex=t_3_l_1.style.z-index;
t_3_l_1_zindex=t_3_l_1_zindex-4;

I get an "index is not defined" error. Pls help thx.

don't use the hyphen when reading or writing a style property of an element,

change element.style.z-index to element.style.zIndex.

(Remember to set the property as element.style.zIndex)
