From the docs:

Arg consists of zero, one or two names of hashes (with or without the
leading %) and an optional array as third parameter. The hidden
metacommand will generate hidden fields for all data contained in the
first hash but not in the second hash

I guess this should do the trick (it works for me):

[- %tmp = () -]
[$ hidden %fdat, %tmp $]

looks like everyone has his own problems with hidden. :) I've sworn
a lot of dirty words trying to understand under which circumstances
hidden doesn't recognize that the value has already been used in
<SELECT> and reprints it, resulting in "field=value<tab>value" in
the next page the data is submitted to..

anyway, the solution you're looking for is: [$ hidden %fdat $] (as
described in the manual)

Hi,

I'm just having the same problem - what did you do to fix it?

- Robert

I think the key is where your [$ hidden $]
meta-command is...

If you move it to just before your </form> tag, you
should be OK, my guess isthat right now, the
[$ hidden $] is before the select that is getting
multiple values.

[$ hidden $]

is the same as [$ hidden %fdat %idat @ffld $]

what means, take all values from %fdat in the order given by @ffld, but
_not_ the values that are in %idat and make hidden fields of them. %idat
contains the input fields that are already seen by Embperl, so you are right
you must put the hidden just before the form tag, because otherwise hidden
can't know which other input fields are already in the form.

Hope this makes it a little bit more clear

Gerald
