BOAC - I'm disappointed by your response. Yes - there are many threads but if you didn't know that you could enter your own custom fields such as [h]:mm (as I didn't until a few minutes ago) then the previous thread that I had read recently and re-read before posting today is no help at all.
If my question was so dumb why wasn't the one posted earlier today about footers in Word greeted with such similar sarcasm from you? Even though the answer was clearly within Word Help I was still happy to answer and help; although beaten to it by a speedier typist
ASFKAP - thanks for your more helpful response - keeping up the traditions of PPRUNE.
