Hello,

I am trying to build a simple ticketing system in Piklist. In simple terms, I have:

price per ticket – currently set to a default value, will be sent to the form
Select Quantity – 1,2 or 3
Update Total Cost based on price * quantity
I have been trying dozens of different methods, but I cannot figure out how to set $price in the code below:

piklist('field', array( 'type' => 'text'

 ,'field' => 'price'
, 'value' => '20'
,'label' =>'price'

 )) ;

  piklist('field', array(
    'type' => 'select'
    ,'field' => 'master_field'
    ,'label' => 'Master field'
    ,'choices' => array(
      '1' => '1'
      ,'2' => '2'
       ,'3' => '3'
    )
    ,'conditions' => array(
      array(
        'type' => 'update'
        ,'value' => '1'
        ,'field' => 'my_field'
        ,'update' => 1*$price
      )
      ,array(
         'type' => 'update'
        ,'value' => '2'
        ,'field' => 'my_field'
        ,'update' => 2*$price
      )
       ,array(
         'type' => 'update'
        ,'value' => '3'
        ,'field' => 'my_field'
        ,'update' => 3*$price
      )
    )
  ));

  piklist('field', array(
    'type' => 'text'
    ,'field' => 'my_field'
    ,'label' => 'Show/Hide Field'
    ,'value' => 1 * $price
    ,'description' => 'This field is updated by the Select field above'
  ));
