Sub total is not displaying on our Square integrated form

Hi, I linked my Square account for my Trivia Night Registration form and clicked the "display subtotal" box in the settings but no subtotal is appearing on my form. I need my registrants to see how much they're being charged before they enter their credit card number. Is there something I'm missing? Thanks, Laura

Please note that the sub total shall be displayed only when the sub products or options added to the products in the payment field. Please go through the guide below that can help you with this.
