Thanks for the replies. I didn’t know about the times differences, but they seemed OK. Adding the brackets didn’t fix it either.
I do seem to have it all working again from older versions of pages, so not sure what happened, especially as it was acting up in phpMyAdmin.
My head hurts now though, as I basically have some code to display different messages and dates depending on where 0/4 images have been uploaded, or if they all have been but any haven’t been updated in the last 90 days.
