[SOLVED] Cart button "disabled"

[goosedesign]

I've just spent ages fiddling with my template files to try and figure out why my "add to cart" buttons have stopped doing anything on my product pages, when I looked at the selected source code to find:

<input disabled="disabled" name="Submit" value="Add to cart" class="exclusive" />

It's not the blockcart module as I've just uploaded the original.

DEVELOPMENT:Have just spotted a sorry looking squashed "transferHelper" div at the bottom left of my page. That's the grey box that's supposed to be the add to cart animation.

SILLY SILLY SILLY: All caused by #image-block in the stylesheet not having a height! What a waste of an afternoon!
