Pricing on details pages

Hi, I am new seller on Amazon, and having created a parent product, and seven child variations, i find that the finished detail page does not include my price, unless i click on a size selection, but given that a the price is the same, irrelevant to size chosen, i would prefer the price to be available on the detail page, so that customers can make an informed choice, can someone tell me how i go about making my price display on the detail page please?,I am of course aware that the parent does not have a price.
