Hi all,

We're using CiviCRM for our new site, and I'm modifying some stuff to get what we need. Might not be best practice, but I need to understand if there is something I should know about how does civicrm/contribute/transact work in order to understand the following:

I'm using this javascript code in my page.tpl.php template file, it's part of a function that runs when in a contribution page form, it receives the amount to prepopulate the form with as a GET variable in the URL:

if ( vars['amountOther'] ) { //GOT VARIABLE AFTER SLICING URL
document.Main.amount_other.value = parseInt ( vars['amountOther'] - 0 );
}
As you can see, I update the "Other Amount" field with the value in the GET variable, so that when I go to http://example.com/civicrm/contribute/transact?reset=1&id=6&amountOther=3750, the field is pre-populated with the amount of 3750 dollars...

...BUT, when I click on Contribute button, it sends me back to the form, saying "Contribution Amount is a required field". I must say I have suceeded in pre-populating the pledge radio buttons to "pledge on" if in the previous page the user has opted so, and the value of the radio button is sent perfectly.

How is the value of amount_other processed? Which might be the problem?

Thanks so much in advance!!

OK, I got it now. Thanks Lobo, that did the trick.
