Cannot find embedded code for calendly on my site

Hello, I added html code for the Calendly pop up communication window on the footer of  my website page (believe it was portraits)  and now I cannot find it, it is popping up on every page. I did check advanced settings for every page -not there. I did  find the code at Website tools- Code injection - footer and deleted it, but it did not work, it still active.  My template is older Version 7.0– Wexley family (Wexley template), Can be that a reason and I wonder what to do to delete that code. my website is lanaellisonphotography.com

It looks like you need to:

1. Click to edit your footer

2. Find the code block in the footer

3. Delete the code block.
