I appreciate if someone can show me how to do calculations in DTML. I am having a problem with Total variable in the example below. TQ in advance. Data_form ----------- <form method="post" action="Data_validate"> <table> <tr><td> Enter quantity: </td> <td><input type="int" name="quantity" value="1" /></td> </tr> <tr><td> Enter Price: </td> <td><input type="int" name="price" value="1" /></td> </tr> <tr> <td><input type="submit" name="submit" value="Submit" /></td> </tr> </table> Data_validate Method ---------------------- Price is <dtml-var price> <br /> Quantity is <dtml-var quantity> <br /> Total is <dtml-let expr="Total=price * quantity"></dtml-let> <br />
