sorry, continued.

<script language="JavaScript">

function addone(){

textbox1.value=eval(textbox1.value + 1)

form1.submit()

}</script>

[html]
<form method="post" action="somepage.asp" onSubmit="addone()"><input type="text" name="textbox1"><input type="submit" value="submit"></form>[/html]

Or more like:

<script language="JavaScript">

function addone(){

textbox1.value=eval(textbox1.value + 1)

}</script>

[html]
<input type="text" name="textbox1"><input type="Button" value="submit" onClick="addone()"></form>[/html]

Re: text box value in asp

I think this will do it. Tell me what you think...
[html]
<html><head>
<script language="JavaScript">
function addone(){
form1.counter1.value=eval(form1.counter1.value) + 1
form1.submit()
}</script>
</head><body>
<%
countsofar = CInt(Request("counter1"))
ddselected = CStr(Request("dropdown1"))
textbox1now = ddselected & countsofar
%>
<form method="post" action="test.asp" name="form1">
<select name="dropdown1">
<option value="a" <%if ddselected="a" then response.write("selected") end if%>>a</option>
<option value="b" <%if ddselected="b" then response.write("selected") end if%>>b</option>
<option value="c" <%if ddselected="c" then response.write("selected") end if%>>c</option>
</select>
<input type="text" name="textbox1" value="<%=textbox1now%>">
<input type="hidden" name="counter1" value="<%=countsofar%>">
<input type="button" value="submit" onClick="addone()">
</form>
</body></html>
