Ok thanks.
I just meant an onblur event , opposite of onfocus. So when the user tabs out of a field. Not an actual blur effect.
The conversion and coding are quite straight forward, I’m just no clear where I’d put the code as it’s being created by ACF.
Here’s a version of what I mean. Fill in the miles tab to the Kilometres and it auto fills.
Would you be able to suggest where or what I might target using the ACF plugin?
Thanks again.
