Search Code does not work for some reason ??

I have tried multiple guides, but landed on one from Wix. I followed the guide but can’t get this search to work. I need people to be able to search between Stations. Its the first column in the database as seen on the picture. But the error seen on picture two comes up every time. When hovering over the dynamicSquare it says #dynamicDataset. Someone please hemlp me on this. Im lost.

All the best
