Sure thing!
First, add a new state to the Popup called “Displayed” with a data type of “number”.
Instead of doing another search, you want to refer to the list of reviews within RG1. Your popup should have a data type of Review, and the Data Source should be “RG1’s List of Reviews: item #: Popup’s Selected” (referring to the state you just created).
When the first image is clicked,
- Set state of element Popup: Current Cell’s index
- Show Popup
Now for the left and right buttons, you do this action:
- Set state of Popup: Popup’s Displayed +/- 1
(plus for right, minus for left)
You should hide the left button if Popup’s Displayed is 1, and you should hide the right button if Popup’s Displayed = RG1’s List of Reviews:count.
There’s multiple ways to do this kind of thing, but hopefully this one is straightforward for you.
