Here are three files, testclick7.php [the whole file] and a code snippit from Purchases4.php [testor.php] and the callback function tor testclick7 [testClickcallback.php] and Purchases4. I am trying to duplicate in Purchases4 what I do in testclick7; ie, to click on a customer name and retrieve the numeric customer id.

The AJAX call works in testclick7 but fails in Purchases4.

The error message I receive is on the following line:

echo "<td><span id='name$i' onclick='getCustNo(name$i)'>$ln </span></td>";

error: reference error: 'getCustNo() is not defined.


testclick7.php:
