I am looking for assistance in executing PHP scripts.
I am running the scripts locally in the C:InetpubwwwrootLocalTest.
System:
XP Pro
IIS
Dreamweaver MX
I successfully ran a "hello world" script.
I downloaded a simple calculator and tried to run it. I recieved the following:
**********************************************************
Notice: Undefined index: n1 in c:inetpubwwwrootlocaltestsimpcalc.php on line 34
**********************************************************
n1 is the value of the first number in the calculator.
What does undefined index mean?
Can you point me in a direction?

I'm not sure whether its an array or normal variable. php has property that makes variable declaration implicit, i.e. u can use variable directly without declaring it. However, i forgot how to declare one explicit and how i made it implicit again. If the problem continues, i can search for u.
Good luck
