The flex repeater passes in a "secret" **index** parameter. The index number is the array number. ![Repeater index](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/3/9311f06f08db8f4781f6cd41adabf9cc654b8da1.png) _Figure 1. The instance index._ On the repeated view add the `index` parameter. I've set it to -1 so I know if it is the test value or the real index value. ![Subview index](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/3/835390cbfd62fdb793d18868ebe5b461d3d1d284.png) _Figure 2. Add the index parameter on the subview._ Now, 1. Pass the index parameter to your keypad popup. 2. Include the index number in the keypad sendMessage. 3. On the subview message handler check the index number. ![Message handler index](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/f/7f79b77d429ad50184b197962462893b25a5e8c6.png) _Figure 3.

The easier solution is something someone else mentioned that should fix it (I'll update my Exchange submission with this update/fix as well, but for now, make the following changes: Add a custom value property under the existing keypad custom property named "ownerId" (should look like this): ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/b/1b761a7a65ba37214ee3ebefebf7b9bcabf1e7e3.png) Change the onMouseDown event script on the numeric entry to: ```auto self.custom.keypad.ownerId = str(system.date.toMillis(system.date.now())) owner = self.custom.keypad.ownerId popParams = {'owner': owner, 'min': self.props.inputBounds.minimum, 'max': self.props.inputBounds.maximum, 'oldValue': self.props.value, 'units': self.custom.keypad.units} posit = None if self.custom.keypad.centerScreen else {'left': event.clientX, 'top': event.clientY} system.perspective.openPopup('keypadPopup-' + owner, 'Exchange/Keypad/Numeric Popup', title=self.custom.keypad.title, params=popParams, position=posit, showCloseIcon=True, draggable=True, resizable=True, viewportBound=True, modal=True, overlayDismiss=True) ``` Change the keypadReturn message handler to use this instead: ```auto if self.custom.keypad.ownerId == payload['owner']: self.props.value = float(payload['value']) ``` Similar changes can be made to the other keypad popups, but this should hopefully solve your issue. ---

Hi, I've followed your guide and I've got to the point where the numpad is popping up but, after pressing Enter, my new value doesn't register. ---

Most likely, you're missing something. Check everything in my example view (Test Keypads) especially the mouseDown event and the keypadReturn message handler script. The event passes the owner to the keypad so that it can properly return the value. Then the message handler script sets the value of the component to the value returned from the keypad. If you're missing either one, it won't work. ---

So the issue turned out to be spacing in the script. When I first copied your script from your post above, it looked like this: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/8/f8899903fa80690206b3c6707962d73ab6d20f87.png) After fixing the spacing, it worked: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/3/73af9e96bca52f34bbe560fd4997fd72e320c701.png) ---
