Thank you both for your help. What was happening is when I clicked on the email box with an attachment it was blank and I could not enter an email address to send it. Once I took the attachment off the email box was fine. It is working fine now so I do not know why it didn’t work this morning.
It all works brilliantly with the customization as I can monitor the status of the quote right through from the work in progress to the job complete. It is brilliant and makes my life so much easier to see at a glance which quotes are pending, accepted with PO’s, work in progress, problem…you name it I can monitor it…so many many thanks.
