I have a text field in which a number is coded by the user, this number goes by php to a database and retrieves information.

That was easy. In the submit button: on (release)
Code:
{getURL("http://admin.cglship.com/tracking/ts2000tracking_DJG.php", "_blank", "GET");
input = "";
}
and in the text field: var: input
and in the timeline: method = "HA200";

Now, the client needs 3 more fields and he wants me to use the same variable $input to retrieve the 4 numbers, separated by a coma.

I dont know how to retrieve the information from the 4 fields, and added to the input variable... "input = "1, 2, 3, 4";

Please you help is necessary!
Thank you
