How to add Next/Previous Buttons

Hello, first thanks for this amazing module, not so easy to get hold of but very promising and very powerful.

im using the modest-grey50p with some adjustments i made to the css to my needs, anyway, im not using a pager and i want to tell the cycle to use some buttons i added to my theme (outside of the ddblock) i tried to add some lines to the custom jquery option :
but all it did is messed my ddblock.

is there any tip that, or guidelines ?

Thanks, and keep up good work.
