Booking form not display if price removed

Hi
I am setting up this theme and facing a problem.

When I removed the price from the WooCommerce ( because I put all pricing in inner tour options ) the tour page iHs not showing the form. I put the options to choose for pricing but need to show the form on the page without the main price.

And how to hide the pricing on tour page unless the visitor choose any of the option.

Thank You
Kind Regards
