Need user input box to automatically insert text from Var

I have a page for users to key in their contact information but I also have some hidden user input boxes that I would like to have automatically fill in using stored values. I need the values to be submitted to the database with the contact information. So far all I have been able to figure out is how to set the placeholder. When I submit the form the placeholder data does not go into the database though.

Here is what I currently have for the placeholders:

$w(‘#input10’).placeholder = pmtdata.itemName;
$w(‘#input11’).placeholder = pmtdata.amount;

For the screenshot I unhid the two fields. As you can see they say EVENT TICKET and 125. BUT that text is not keyed into the fields. I need it keyed into the fields so that it goes into the database with the rest of the data.

Any help with this would be appreciated. I’ve been searching for a solution for hours. I’m extremely new at javascript and basically am figuring it out as I go…

Ok, so I finally figured it out. For anyone else that needs to know you can have a variable automatically placed into an input field with the following type of formula:

$w(‘#input10’).value = pmtdata.itemName;
$w(‘#input11’).value = pmtdata.amount;
