Hi John
You work ever so hard, so many replies to so many people you deserve a medal.
Thank you for the detailed answer, it looks like I go down the PHP route. I’ll have a play with the code you posted I assume it goes in functions.php?
BTW the way I have wondered as I have seen it in other pieces of code, what do the numbers mean at the end of add action element in this instance 20?
Thank you once again
