Trouble Executing PHP Scripts

svp28svp28 Member Posts: 1
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?

    Hi,

    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
