Hi Joel...
Unfortunately, you are not giving us HALF the elements we need to help you there:
- Looper: ajax or not?
- code of the link: browser or server
- settings of the link: send value of controls to the server or not?
all these elements influence how your page/looper/controls are going to behave...
In principle, yes, LooperName returns the index of the currently selected (or clicked) line of a looper, but it depends of many different elements
Best regards
