I took a second look onto your CODE → HOUSTEN WE HAVE A PROBLEM :grin:

I have tried to give your CODE some structure, although not everything was clear

Try to replace your old with this one and test it.

import wixData from 'wix-data';

$w.onReady(function () {
    $w('#clear').onClick(() => {
        $w("#locationDropdown").value = undefined
        $w("#dropdown3").value = undefined
        $w("#dropdown4").value = undefined
        $w("#buildingdataset").setFilter(wixData.filter().eq('typicalFloorPlate', location))
        $w("#buildingdataset").setFilter(wixData.filter().eq('location', location))
    });

    $w('#search').onClick(() => {
        $w("#buildingdataset").setFilter(wixData.filter()
        .contains("location", $w("#locationDropdown").value)
        .between("typicalFloorPlate", parseFloat($w("#dropdown4").value), parseFloat($w("#dropdown3").value)))
        .then((results) => {console.log("Dataset is filtered");
            $w("#repeater").data = results.items;
        })
        .catch((err) => {
            console.log(err);
        });
        $w("#repeater2").expand();
    });
});
