handbookPop is not defined because you are sending an undefined value
to your function setStyle function. Change it to the following
accordingly:

setStyle("handbookPop", "display", "none");
setStyle("handbookPop", "display", "");

handbookPop should be a string.

But when I use a <body onLoad="javascript:hideDiv();">
<a href="#" onClick="javascript:showDiv();">show div</a>

Javascript pseudo-protocol is a very bad practice. Try searching the
groups here, and you'll get many reasons as to why it is so.
