I have two form fields getting their record from a data base, they both get numbers, and in the same form, I would like to add a third field, and then get it value by putting the two other fields together,

Here is what I want:

I have:

x = field one (get value from database, Number)

y = field two (get value from database, Number)

I would to have as final result:

z (form field three) = x + y

Java or whatever else that work, (I am using Dreamweaver CS5)

thanks

I assume that you are working with a server side code in which case just use that.

For instance, if using PHP the example would look like

<?php /* the following values will be obtained from the database*/
$rowDatabase['x']=53;
$rowDatabase['y']=104;
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<input name="x" type="text" readonly="true" value=<?php echo $rowDatabase['x']; ?> /> +
<input name="y" type="text" readonly="true" value=<?php echo $rowDatabase['y']; ?> /> =
<input name="z" type="text" readonly="true" value=<?php echo $rowDatabase['x']+$rowDatabase['y']; ?> />
</body>
</html>

Wappler is the DMXzone-made Dreamweaver replacement and includes the best of their powerful extensions, as well as much more!

Please explain how the 2 fields (x, y) are getting their values. Are they populating a list box that the user selects a value from, or just a single value from the recordset? If the latter, then you can just add a calculated field to the recordset:

Select x, yb, x + y as total from MyTable

If the former, then you need to tell us how the sum will be used.
