product image next & prev buttons

[Creepzn]

I've been reading a lot of posts about this error where next and previous button in fancybox either don't show or don't work.

I have the issue where mine don't work

Have tried tons of solutions, and managed to get the buttons to display, and got the close button working, but clicking the nav buttons does nothing.

Does it work OK with Protostar?

[Creepzn]

It will work with protostar, but like before, I'm using gantry framework and forgot to mention that actually.

The fancybox buttons don't seem to work properly on this framework. Everything else works beautifully, but the gantry forum is something like $59 to sign up and the exchange rate is definitely not in my favour

so I posted here and am hoping for someone smarter to point me in the right direction.

In the jquery.fancybox-1.3.4 the css is
#fancybox-left, #fancybox-right {
    position: absolute;
    bottom: 0px;
    height: 100%;
    width: 35%;
    cursor: pointer;
    outline: none;
    background: transparent url(../images/fancybox/blank.gif);
    z-index: 1102;
    display: none;
}

which I edited to display:block
which then shows the arrows, but clicking on them doesn't do anything
