Not able to perform computation on Non Database Column in Tabular Form

Question

Hi All,
          I have a Master and a Detail Tabular Form which has the following requirement:
If I choose Two Way in my Trip Type item in my Master form,the  No of Tickets field in my Detail Tabular form has to get doubled ie. 2*No of tickets
The No of Tickets is a Display as Text(does not save state) field so I am not able to select the value of the field in jquery.
Kindle help me with this.
Thanks and Regards,
Madonna

I have added a true and a false action to the dynamic action disable.
Here is the code of the false action. The action type is Execute JavaScript Code
/*Select all input elements with the name attribute f14*/
apex.jQuery('[name="f14"]').each(
  function(){
    var lNoTickets,lSpan;
    /*Calculate the number of tickets by getting the value and times 2*/
    lNoTickets =(this.value*2);
    /*Determine the display element*/
    lSpan = this.nextSibling.nextSibling;
    /*Set the new number of tickets to the display element*/
    apex.item(lSpan.id).setValue(lNoTickets);
     /*Set the new number of tickets to the hidden element*/
    this.value = lNoTickets;
Because you have used "Display as text(saves state)" apex renders both an input item of type hidden. And a span element that displays the value.
Both these elements need to be set separately. See the last two lines of the code.
The calculation of the new Number of tickets happens for each hidden element with the name f14.
And the span element is the second sibling of the hidden element.
