The problem is that the current PmWiki radio button markups do not
allow you to preset values, the same with checkboxes, textareas,
selectboxes, etc.  It's kind of a problem with PmWiki.  It is not
really a ZAP limitation.

I wrote my own Markup for selectboxes and textareas, that help and
suppose I could do the radio boxes and checkboxes also, but would have
to settle on a syntax and work out the code, which I don't have time
for just now.  Maybe someone else does?

Also, I haven't done it because Pm has said the whole forms script
will be updated soon.  In which case  my forms markup will probably be
deprecated.  Pm, any news on how long till this may be?

Actually it is possible right now if you use a bunch of conditionals,
for example with a simple checkbox you could do the following:
(Warning--these are off the cuff, and may not be exactly right, but
will give you an idea).

(:zapdata:)
(:if equal {$cb} "on":)
(:input checkbox cb checked:) Test
(:if ! equal {$cb} "on":)
(:input checkbox cb:) Test
(:if:)

For radio button it's more complex--for you have to do the same basic
lines for each button (lines 2-5 at least).  But it can be done, and
it's available now.

Let me know if I can be of any more help.
