Crayon with Advanced Custom Fields

i read your response to a cimilar issue on github but when i applied the solution on my site the code did not hishlight.

https://github.com/aramkocharyan/crayon-syntax-highlighter/issues/67

i am using Advanced Custom Fields and a nested repeater field which is

echo $row['sub_section_content']

so i made it:

echo CrayonWP::highlight($row['sub_section_content']);

and still no highlighting even though the <prev> tags gets added.

any help would greatly be appreciated. besides for this issue it has been the easiest and most succesful highlighter we have used.

thanks-
