XmlConnector with next, previous and zoom

hi all,

I made the old and accient xmlconnector application through a tutorial…
I have been trying to add a next and previous button to it with no result so far…

I have one combobox, a textarea and a imageloader that are all conected to one xml with the xmlconnector.

The thing is if i select a subject in the combobox everything changes. if i take the next symbol it should go to the next item in the list of the combobox…
same for the previous button.

also i have a zoombutton for the images… i just want to load the image in a new window at full size…

how can i do this…?

Thanks in advance
