Template repeater not passing parameters to popup

Hello, im attempting to pass the parameters from a template repeater using dataset mode into a popup however it seems that none of the custom properties are being passed from the repeater template on click into the popup window.

Show your code that opens the popup. What event are you using?

The popup is being launched from a button inside the template that's being repeated? Are you sure the template is receiving the custom properties from the repeater's dataset?

Check the simple stuff like capitalization and spelling. These are the biggest gotchas for this sort of thing.
