Yeah, don't hardwire the "return false" :-) Something like this --

<a href="foo.html" onclick="return(foo());">

function foo()
{
     var result = true;
     if (document.getElementById)
     {
         // Blah, blah, blah...
         result = false;
     }
     return result;		
}

And note: there's only *one* place in the code -- the very end --
that the result is returned, though the *value* to be returned can
be set multiple places; generally considered easier to troubleshoot...

FWIW,
