Portal row navigation with forward/back buttons

[Matt.C]

I'm hoping someone might be able to help, or at least point me in the right direction.

I'm creating a portal that displays a student photo, but would like the ability to navigate forward/backward through the photographs in the portal without the vertical scroll bar. My < and > buttons currently point to a Go to Portal Row - Previous/Next script step. It works great when "Allow vertical scrolling" is turned on, but does not work with it turned off. 

It does work with Allow vertical scrolling turned on and show scroll bar set to "When scrolling", however, the scroll bar appears on mouse-over. 

Any suggestions on how I might be able to achieve this?

Many thanks!

How exactly does it work? You seem to have a field to display the current row's image. What is this field and how is it currently populated?

I have two tables, Student and StudentPhoto, that are connected via an ID field. The portal on the student layout shows the container field (with the photo), and the photo date feidl, from the related records in StudentPhoto. 

I've attached an example file below showing what I've done...

Thanks!

I see. Well, you can't scroll a portal if you don't allow scrolling. I suggest you use a filtered portal instead, with a global variable or field storing the number of the child record to show - see the attached demo:

Thanks @comment for the demo. I hadn't thought of using portal filtering like that!
