What is the scope of variables in the included script? Are they local to the function that calls include with the file name? Thanks in advance; I'm not sure where to look for this answer; JK

FYI, I just ran a quick scope test based on my guess of your situation. If you include a PHP file containing global variables inside a function, the variables will _only_ be available after you include the file, and only for the duration of the function. They will not exist after the function ends, even if you specify global $var1; in your other functions, or at the global level of your script. This was tested using PHP 5.0.4. Here is my sample code: test.php: <? print "Top Level: Var1: $var1 Var2: $var2\n<br>"; test1(); test2(); function test1 () { print "Before: Var1: $var1 Var2: $var2\n<br>"; include("testinc.php"); print "After: Var1: $var1 Var2: $var2\n<br>"; } function test2 () { print "Test2: Var1: $var1 Var2: $var2\n<br>"; } print "Bottom Level: Var1: $var1 Var2: $var2\n<br>"; testinc.php: <? $var1 = 1; $var2 = 2; ?>
