custom field issue

Hi people,

I am having an issue with the advanced custom field plugin. I added a custom field called ‘image’ and at first there was the option of browsing and selecting an image – which would then display. Now however, something has changed and I have to asign this image a ‘value’ (a number – which the client is not going to be able to do). Can anyone suggest why? I’ve tried reinstalling it to no avail 🙁
