Hi,
Please ensure that you have a layout selected under the Popupbox layouts. You can refer to this screenshot for guidance: https://imgur.com/qZ1rOYT
Next, check that you have set the trigger properly. To do this, identify which team layout you have selected and enter edit mode. You can find a reference screenshot here: https://imgur.com/Pa2L1YT
For example, if you want to display the popup when clicking on the team member’s title, expand the ‘title‘ element. Make sure that the “link to” option is set to “popup box.”
