Asp form

Hi, I am new at asp and I don't know much about programming. I am trying to create a form that does some calculations. I am using dreamweaver and i have inserted a list/menu in my form but i can't connect the values from the form with the source code. What I have done is this:

<form action="calc12.asp" method="get">
<table width="820" height="291" border="1">
<tr>
<th width="140" scope="col"> </th>
<th width="664" scope="col">Υπολογισμός</th>
</tr>
<tr>
<th height="112" scope="row"><label for="select"></label>
<select name="deiktes" id=Select1>
<option value="noneSelected"> Λίστα Επιλογής </option>
<option value="Ενεργό πλάτος λεκάνης απορροής"
<% if deiktes="Ενεργό πλάτος λεκάνης απορροής" then response.write("SELECTED") %> > Ενεργό πλάτος λεκάνης απορροής</option>
<option value="Αδιάστατος Δείκτης Κυκλικότητας RC"
<% if deiktes="Αδιάστατος Δείκτης Κυκλικότητας RC" then response.write("SELECTED") %> > Αδιάστατος Δείκτης Κυκλικότητας RC</option>
<option value="Αδιάστατος Δείκτης Επιμήκυνσης"
<% if deiktes="Αδιάστατος Δείκτης Επιμήκυνσης" then response.write("SELECTED") %> > Αδιάστατος Δείκτης Επιμήκυνσης</option>
<option value="Αδιάστατος Δείκτης Συμπαγούς"
<% if deiktes="Αδιάστατος Δείκτης Συμπαγούς" then response.write("SELECTED") %> > Αδιάστατος Δείκτης Συμπαγούς</option>
<option value="Πυκνότητα υδρογραφικού δικτύου"
<% if deiktes="Πυκνότητα υδρογραφικού δικτύου" then response.write("SELECTED") %> > Πυκνότητα υδρογραφικού δικτύου</option>
<option value="Συντελεστής ελικτότητας κυρίου υδατορρεύματος"
<% if deiktes="Συντελεστής ελικτότητας κυρίου υδατορρεύματος" then response.write("SELECTED") %> > Συντελεστής ελικτότητας κυρίου υδατορρεύματος</option>
</select></th>
<td><p class="asp">
<label for="varA"></label>
<input type="text" name="varA" id="varA">
</p>
<p class="asp">
<label for="varB"></label>
<input type="text" name="varB" id="varB">
</p></td>
</tr>
<tr>
<th height="122" class="asp" scope="row"><input type="submit" name="Submit" id="Submit" value="Submit"></th>
<td class="asp"><label for="theAnswer"></label>
<label for="theAnswer"></label>
<input type="text" name="theAnswer" id="theAnswer"></td>
</tr>
</table>
</form>
That is the code of the form.

<%
theVarA = Request.Querystring("varA")
theVarB = Request.Querystring("varB")
thedeiktes = Request.Querystring("deiktes")
%>

<%
if thedeiktes = "Ενεργό πλάτος λεκάνης απορροής" then theAnswer = theVarA / theVarB
if thedeiktes = "Αδιάστατος Δείκτης Κυκλικότητας RC" then theAnswer = ((4*3.14*theVarA) / (theVarB*theVarB))
if thedeiktes = "Αδιάστατος Δείκτης Επιμήκυνσης" then theAnswer = ((2/theVarA) * (sqr(theVarB) / 3.14))
if thedeiktes = "Αδιάστατος Δείκτης Συμπαγούς" then theAnswer = ((0.282 * (theVarA)) / sqr(theVarB))
if thedeiktes = "Πυκνότητα υδρογραφικού δικτύου" then theAnswer = theVarA / theVarB
if thedeiktes = "Συντελεστής ελικτότητας κυρίου υδατορρεύματος" then theAnswer = ((4*3.14*theVarA) / sqr(theVarB))
%>

<body bgcolor="#C0DFFD">
<%Response.Write "theAnswer"%>

</body>
And that is the asp code
Please help me if possible.Thanks in advance

The problem is that you are using

Code:

Request.QueryString()

but you are not passing the variables as query strings. Query Strings are useful in OTHER situations, but not here... in this case you have direct access to the variables.

I think all you need to do is change the Request.QueryString()
to:

Code:

Request()

and you'll be good.

Change the first line in your form from:

Code:

<form action="calc12.asp" method="get">

Code:

<form action="calc12.asp" method="post">
