Hi,
you could use the concat - function to generate the list of possible values for the inputbox.
I.e.you have two variables var1 and var2 and a field called date1:
The list of restricted values for var1 is calculated like this: =concat(Datum, ';', Datum )
and for var2 only dates that are >= var1 are shown: =concat({$<Datum={">=$(Variable1)"}>} Datum, ';', Datum)
I attached a qvw to this post that demonstrate my approach.
I guess that should solve your problem.
Cheers,
Gerald
