Prefill Form Field - Form Builder

I have created a technical support survey form. I'm using OSTicket for my tech support ticketing system.



I want to pre fill one item in my form (Ticket Number). I know this is normally done in the URL but I cannot seem to get the URL code correct.



Here is the URL with the code I'm trying to use:

http://www.vertical-sbx-mbx-telephone-voip-systems.com/index.php?dispatch=pages.view&page_id=50?Ticket%#=998759



The original page url is:

http://www.vertical-sbx-mbx-telephone-voip-systems.com/index.php?dispatch=pages.view&page_id=50



Is there anyone that can help me understand what I'm doing wrong? I have tried using the label “elm_240” and also "form_values[240] in place of “Ticket%#”.



Here are the form properties from the code:








Thanks so much in advance if you can assist!

I'm trying to create a link to a form from a product which when clicked auto fills in the product name in the form, how can this be done?

Try some jQuery like:

]code] ```

If you can add product_id to the URL, use


```php


```



where elm_240 is the ID of the required text input
