Hi,
Example:
- Field1_City:
- Field2_Streets (Listbox)
Feld2_Streets shoud list only the Streets from the entered Field1_City (not
all Streets)
Thanks,
rainer kaelin

2 alternatives that I can think of and only one makes sense due to the
possible number of streets...both involve javascript
1) store all streets in a js array and filter in on the fly (too many
records really)
2) make the city field a html field and add an "onchange" event to it that
calls a js function
the js function would take the value and submit the page back to the
server similar to
newLocation = "MyNewPage.asp?" + transfer_stuff + "&myCityParam=" +
document.MyPageName.MyCityField.value ;
document.location = newLocation;
The above snippet (you'll need more but this is a start) will repost the
page with your MyCityParam that will tell you new page to fill in the
dropdown with the streets for this city
3) the redisplayed page should now have the city and a dropdown of the
streets to that city (btw, a dropdown of a city like Chicago or New York
might be way, way too large to handle with a dropdown)
Anyway, it is not as easy as I make it to be...it can be done...I've done it
in several places but it can be done. BTW, debugging js code sucks!

thank you!
The City, Street was only a example. The real table has only 40 Record.
Kindest Regards
