Change asp variable value from selection options

You have to collect user entered data in ASP either through a submitted form, or a particular querystring link.

So for a drop down, the user would have to choose thier selection, then hit a submit button. Keep in mind however you can have the form action be set to submit to the very same page and just pass a flag to indicate that.

Once its submitted you can get the value. Even if you are populating your drop downs with javascript or using javascript to control thier interactions with it.

For example:

Code:

<form action="mypage.asp" method="post">
<select name="dd1">
<option>Whatever</option>
</select>
<input type="hidden" name="Mode" Value="S">
<input type="submit" name="btnSubmit">

'Bottom line is just put the following code then at the top of your page to handle the collection of this data. 
dim MyMode
dim MyDropDownValue
MyMode = request.form("Mode")
if MyMode = "S" then
     'get your value
     MyDropDownValue = request.form("dd1")     
end if

Is this what you needed\help?

As a further comment to Jeff's excellent answer, you could also have your form automatically submit using javascript once an option was selected from the drop down.

This is what I ended up doing. I've ran into another problem though, and not really sure how to get past it. The page I created needs to be refreshed every minute. When the page goes to refresh it pops up that message that data needs to be resent to the server. This is because I have a POST form on my page. How can I get around this so that the message doesn't come up, and the page automatically refreshes??

I don't believe it's possible to disable the message - it's there to stop people from accidentally resubmitting data which could lead to them doing things like paying for items twice.

I see two possible solutions to your problem.

Rather than refreshing the page when the timer hits the interval you could redirect the page to itself. You would lose any request variables (unless you passed them through the querystring) but you wouldn't get the re-posting message.
You could use AJAX to refresh only the portion of the screen that you are interested in - check out this tutorial on the basics of AJAX for some more info.

Hope this helps,
