#21 Remember previous typed parameter-values

[spreadshirt.com]

When i use a report with parameters which are marked as
required and I have forgotten one of them, then the
site is redirected to the parameter-form and shows the
error, that one field was not filled ...
But the other already filled parameters have lost the
previous values ...

It would be great if thoose values would be reminded if
goes back to the form ...
This also could be used with the default-values which a
have requested in the previous post ...
