I'm trying to make a form where it would automatically update the total based on the ticket they have chosen (radio button) & additional donation they want to give (textbox). The textbox I have no problem with but the radio button doesn't add. Can anyone please help? Thank you. <html> <head> <SCRIPT language="javascript" type="text/javascript"> function updateTotal() { var ticket = 0; for (i = 0; i < 7; i++){ if (document.forms["secureform"].test[i].checked == true){ ticket = '' + (document.forms["secureform"].test[i].value * 1));} document.forms["secureform"].totalAmount.value = '' ((document.forms["secureform"].contribution.value * 1) + (ticket * 1)) ; } function updateFamilyTotal() { document.forms["secureform"].contribution.value = 0 updateTotal(); } //ends function </SCRIPT> </head> <body> <form method="POST" action="#cgi.script_name#" name="secureform"> <table> <tr> <td colspan =2> <input type="radio" name="ticket" value="10000" onClick="updateTotal()">Running the Race Table (10 Tickets) -$10,000<br> <input type="radio" name="ticket" value="7500" onClick="updateTotal()"> American Hero Table (10 Tickets) -$7,500 <br> <input type="radio" name="ticket" value="5000" onClick="updateTotal()"> Freedom Fighter (10 tickets) - $5,000<br> <input type="radio" name="ticket" value="3500" onClick="updateTotal()"> Founding Father Table (10 tickets) -$3,500<br> <input type="radio" name="ticket" value="2500" onClick="updateTotal()"> Patriot's Pride Table (10 tickets) -$2,500<br> <input type="radio" name="ticket" value="800" onClick="updateTotal()"> Flag Bearer Table (2 tickets) -$800<br> <input type="radio" name="ticket" value="250" onClick="updateTotal()"> Stars and Stripes: Individual tickets, $250 per person <br> <br> </td> </tr> <tr> <br> <td align="CENTER" width="500">Additional Contribution<span class="colB font-size: 10pt;"><br> <input type="Text" name="contribution" value="#contribution#" size="5" onChange="updateTotal();"><br> <p>Total Contribution (contribution plus ticket prices): $ </p> <input type="text" name="totalAmount" readonly="true" style="width:50px;"> </span></td> </tr> <input type="submit" value="Submit"></td> </table> </form> </body> Code (markup):
