Required fields on submit button code

HI, I would like my required fields to error if they are not entered, just like they do normally when you connect them.

However, as I am using code to submit my data etc, this doesn’t work.

I have tried with the below code use the .valid property but it doesn’t work at all…

Any advice? Thank you!

export function submitButton_click(event, $w) {
	let updates = {
		"address": $w("#streetAddress").value,
		"unitNumber": $w("#unitNumber").value,
		"city": $w("#city").value,
		"state": $w("#state").value,
		"zipCode": $w("#zipCode").value,
		"propertyType": $w("#propertyType").value,
		"bedrooms": $w("#bedrooms").value,
		"bathrooms": $w("#bathrooms").value,
		"squareFootage": $w("#squareFootage").value,
		"condition": $w("#propertyCondition").value,
		"propertyNotes": $w("#propertyNotes").value,
		"name": $w("#name").value,
		"emailAddress": $w("#emailAddress").value,
		"phoneNumber": $w("#phoneNumber").value
	};
	
	let req1 = $w("#propertyType").valid;
	let req2 = $w("#bedrooms").valid;
	let req3 = $w("#squareFootage").valid;
	let req4 = $w("#propertyCondition").valid;
	let req5 = $w("#name").valid;
	let req6 = $w("#emailAddress").valid;
	let req7 = $w("#phoneNumber").valid;
	let req8 = $w("#bathrooms").valid;
	
	if (req1 === 'false' || req2 === 'false' || req3 === 'false' || req4 === 'false' || req5 === 'false' || req6 === 'false' || req7 === 'false' || req8 === 'false') {$w("#errorText".show);} 
	else 
	{wixData.save("Sellers", updates)
           .then(() => {
           	sendFormData();
             //go to sellers page 
            wixLocation.to("/sellers-3");
           })
           .catch( (err) => {
             console.log(err);
           } );
}}

Have you tried if (req1 === false without the quotes? Boolean is never a string, it is a boolean, true or false
