combobox that limit his choice

[SAN CAZIANO]

ho can i create 2 combobox with this value
1
2
3
4

and when I change the value of the first combobox, if the second combobox
has a value great than the first it must be empty
So the second combobox have to show all the value lesser or equal than the
first


For example
if combo 1 has value=3
combo 2 can't has value=4 but only all the value lesser

So I have to intercept the change of the first combo to change the list of
the second

Thanks

this is usually done with javascript programming, not server side like php.

You can only do this with Javascript, not with other languages
