I am having a problem trying to use iframe code to view a booking system on a website. The code I have been provided with is:
<iframe style="width:100%;height:600px;border:0;" src="https://www.sportsinjuryfix.com/business/booking/new/33852?embed=1&hex1=111&hex1i=dedede&hex2=dedede&hex2i=111"></iframe>
I have tried adding it to a html stack and also using stack4stacks embed stack but in each case the frame size shows but with no content and obviously no border. The https link in the iframe works on its own just fine. I am adding it to a https website so there is no conflict between http and https in the iframe. I have also tried formatting the code but that didn’t make any difference.
Any help would be much appreciated.
