Help With Buttons and Viewer

[dk]

Could someone suggest how I might go about this in Hippo?

I have a Viewer that contains 5 images. I have a "Next" and a "Back" button.
I want the "Next" button to dissapear when the 5th image is displayed.
Tried putting seperate buttons on the timeline but if you press the buttons enough the images in the viewer end up out of sequence.

Is there a way to tag or track the images in the Viewer?

Cheers

Do you have an example you could send me that gets out of sequence?

sadly I deleted the project out of frustration and it took so long to make I don't think I could redo it.

I had 5 images in a viewer and 5 buttons along the timeline. Each time a button was clicked it would move the image in the viewer back or forward. This would take me to a different frame each time the image changed....now I don't know if it was the fault of Hippos viewer ( as I did'nt publish it to html to try) but what was happening is sometimes the buttons would get out of sequence to the Images in the image viewer.
