Hi Larry,
As well as the afore mentioned, all excellent comments, you can use the 'if
exists(fld "myField01") then' script. I also encapsulate all sorts of
things in "try"..."end try" commands. These are extremely powerful although
could be considered a little lazy. For example, when using iPhone
One caveat: if you are assembling a great deal of text in small chunks, you

So is there a way to first find out if the field exists?
Did you look up "exists" in the diction
hink about that.
Thanks,

Why are you creating them and deleting them? Why aren't the fields already
there and you just show and hide them?
