I've spent most of the afternoon, and now evening trying to get this to work. Have tried the ScrollView Examples, but to no avail. Could someone please provide a simple sample which demonstrates the use of ScrollPosition.

Thanks for the :sign0085:

The program below shows it.
I used Buttons just to show the principle, even though with the buttons it is not realistic.

Scrollposition now works

Thanks for the speedy reply.

I cut-n-pasted your code into a blank program script. It worked perfectly
on my device running v 2.2. However it will not scroll on any AVD, AP! Level 8 or 9, or v 2.2 or 2.31.

As often as I can I will now design on an emulator but test only on device.

Thanks a Meg for the assistance.
