Hi
Someone please assist. This is driving me nuts!
If you look at the screen-shots below:
(1) Is the Type that I am using and (2) is what the data looks like.
(3) Is where I am trying to filter (using search) for the selected time in the Bubble Full Calendar.
The text on the calendar page is just there to show you what time has been selected in the calendar.
(4) Is the error I receive when referring to the above element with the selected time.
How do I get past this error?
Any assistance will be appreciated.
Many thanks, Mark.

Fixed. Filter should have been here.
