parsing error: unexpected token $

[frog866]

thankyou, I am now getting an error on line 22 saying
‘parsing error: unexpected token :’

import wixData from 'wix-data';//to work with the collection you need to import this field
export function button1_click(event) {
 for (var x = 0; x <= 3; x++) {//for 4 upload buttons the maximum index is 3
 if ($w("#uploadButton" + x).value.length > 0) {
            $w("#text67").text = 'Uploading ${$w("#uploadButton"+x).value[0].name}';
            $w("#uploadButton" + x).startUpload()
                .then((uploadedFile) => {
 
 let toInsert = {//myImage is the field key for your images column in the collection
 "gallery": uploadedFile.url
                };
                wixData.insert("locations", toInsert)//myCollection is name of the collection to where the images are added
                    .then((results) => {
                        $w("#text67").text = "Upload successful"; //see item below
                    })
                    .catch((err) => {
 let errorMsg = err;
                    });
                })
                .catch((uploadError) => {
                    $w("#text67").text = "File upload error";
                    console.log(Error: ${uploadError.errorCode});
                    console.log(uploadError.errorDescription);
                });
        } else {
            $w("#text67").text = "Please choose a pic to upload.";
        }
    }
}
