Hi Breklin,
I have download it, I haven't had much time today to look at either yours or
Steve's, as i'm off for a few days much needed rest as of tomorrow, but I
have printed both off to take with me. These will no doubt be read whilst
relaxing under an umbrella in the rain:-0
I have as of tonight, (having given it a lot of thought) come round to the
idea perhaps I should use a separate Id field, and have now added this.
Though I must admit I don't fully understand how it would prevent any
duplicates. But as I have little knowledge on which to base any theory, I
felt that as those that did were telling me of it's benefit I would listen
to the voices of experience. And of course I'm going to do some more reading
on this particular topic also.
Have a great week, and thank you very much for the helpful code. I will no
doubt be back next week with question for you both, that is if you don't
mind! As I'm sure there will be things I'm not one 100% on.
Kindest regards,
Linda
