Hello PerlMonks. I have a HTML file that has a form with different text input blocks (Add/Search/Delete)each with different submit buttons. There is a CGI script which takes all text box parameters from the HTML file. However, for each submit button, with "onclick" I want to pass a value(0,1,2 etc) to it so that I can have a switch case 1-Add, 2-Search etc in the CGI script for relevant Add/Search/Delete subroutines. Inside the html file I created a little javascript function as follows :

<script type="text/javascript">
var mysample = '';
function setval(varval)
{
    mysample= varval;
    alert(mysample);
}
</script>

and posted this in the html for two submit buttons: 
<input type="submit" value="Add Entry" onclick="setval(1)" />

<input type="submit" value="search" onclick="setval(2)" />

Also, I added a hidden input to pass the parameter to CGI : 
<td align="left"><input type="hidden" name="mysample" size="15" maxlen
+gth="50"></td>

However, on running the html file, it is not passing the mysample variable value to the CGI. Any ideas?
