Date parameters

This works: *********************************************************

import wixPay from ‘wix-pay-backend’;

export function createPaymentForProduct() {
return wixPay.createPayment({
amount: 60.00,
items: [{ name: ‘Test Purchase’, price: 60.00 }],
} );
}

I’d like this to work but need some syntax help: ********************

import wixPay from ‘wix-pay-backend’;

export function createPaymentForProduct() {

if new Date() >1/1/2022 then VarAmt = 200.00; 
if new Date() >2/1/2022 then VarAmt = 150.00; 
if new Date() >3/1/2022 then VarAmt = 100.00; 
if new Date() >4/1/2022 then VarAmt = 50.00; 

return wixPay.createPayment({ 
	amount: VarAmt, 
	items: [{ name: 'Test Purchase', price: VarAmt}],		 
} ); 

}


Any thoughts?
