Couponsite :Listing setup>Custom fields How to let display custom fields on add

I added custom field like conditions, opening time, normal price, campaign price etc. The problem is that I cant see my filed custom fields at the description of add. I can see them only in case I try to print that offer.Than I can see all this custom field staff.But i wanna see that on single listing of cuopon. Support said me I should put shortcode [FIELDS]somewhere in content-single-listing-coupon.php. But somewhere dont work.You get error message. So can somebody explain me or show screenshot , how should look that “content-single-listing-coupon.php” file together with shortcode [FIELDS]. Or where should I put that, becuase it doesnot work, that you just add shortcode on any place in php file and I am not IT. Support said it my business and that your personal extra option. I say that fcucking standart and I shouldnot know php language for that.
