Hi,

you cant do this in javascript as if you try adn write to the document using any kind of document write format, itll throw a method operator error.

Hees the one I wrote for a project. uses ASP and simple VBscript.

<SELECT id="Tools" style="WIDTH: 116px;" name="tools">
<option value="" SELECTED>Select and Add</option>
<option value="None">Nothing</option>
<OPTION value="Microwave">Microwave</OPTION>
<option value="Toaster">Toaster Oven</option>
<option value="Coffee">Coffee Pot</option>
<option value="Skillett">Electric Skillet</option>
<option value="Demo Table">Demo Table</option>
<option value="Military Access">Military Access</option></SELECT>

<input name="ADD_T" type="submit" value="Add>>" />
<TEXTAREA id="Tools" style="WIDTH: 176px; HEIGHT: 45px" name="ToolBox" rows="2" cols="19"><% call ToolsDisplay() %></TEXTAREA>

so youve got a select box, submit button and text box to stor the info

now heres the function to write the info.

session("Tools") = Request.Form("ToolBox") // textarea form element
 
private function ToolsDisplay()
    
// if the form is submitted and button is not pressed, code wwrites the //session contents into the textarea, errorhandling  code for form 
// kickbacks
if (Request.form("ADD_T") = "") then
with response
.write Session.contents("Tools") 
end with
end if
 
 
// writes the current selection of the select box
if (Request.Form("ADD_T") <> "") then
with response
.write Request.Form("tools") 
end with
end if
 
end function

This code will write th ecurent selection of the select box into the textarea
when pressed, adn when other parts of the form are working, suhch as
a primary submit button, the textarea will show the current session contents, which is collected form the text are when a value is written into the textare.

Therefore this creates a loop where if a person selects 1 set of data, then goes back and select another
the data will be collated rather than overritten.

Its a nice bit of code, althouh a tad convaluted, but neccesssary for optimal performance.

Hope it helps

OMG!!!!

Its a classic when that happens!!!

Wll.. you knwo for next time if you need it. Also

You can use the document.myform.submit() on the on change function in javascript for this if anybodies interested. But this might be confusing to your users as they might think on adding manually..
