but about a nonexisting.

the zsql-method gives me a error message because variable does not exist
where is that documented, i can't find it

<input name:date:ignore_empty="min_date" value=""><input type="hidden"
name:default="min_date" value="">
it doesn't work, what is wrong. i don't understand the conzept either.

is there a way to have <input name:date:optional="min_date" value="">

thanks for help
