Why will my Form not update ??

CroxNix - Many Thanks, It works ! - I am impressed by the stupid mistakes I make !

One very weird behaviour the s/w is exhibiting, which I am uncertain about, is how I might amend a human readable date in the form, like "31 Aug 2011" and I do submit, but 20% of the time the amendment does not 'take' ie it comes back with the old date. So I try again, or I try on a different field and it then does work.

Is this the inadequacy of the strftime function ?

Or perhaps, because my update() is not doing a batch update but rather individual fields ?

Thanks !
