Troubleshooting Code 800A01F4 – Variable is undefined
Introduction to Code 800A01F4
The Symptoms You Get
The script does not execute as you hoped, instead you get a WSH error message.
The Cause of Code 800A01F4
Your VBScript contain is an undeclared variable. Most likely, this is a spelling mistake in one of your variables. The clue here is in the Error:…. ‘DriveLetter11’. Most likely, this was meant to be DriveLetter1 and not DriveLetter eleven.
Examine YOUR Windows Script Host message box, and check your Line :. In my example it’s line 12. The Char : is not much use for error 800A01F4. My point is that rarely is it the very first Char that’s at fault.
Incidentally, Source: reports a runtime error not a compilation error, this means you are looking not for a pure syntax problem, but a fault logic error. In the case of runtime errors, you can use this temporary work around. Add this statement just before the line which errors: On Error Resume Next.
Note: Almost certainly your script has ‘Option Explicit’ near the top.
The Solution for Variable is undefined
Check the syntax of your script. In my VBScript example, ‘DriveLetter11’ on Line 12 is the problem. In your example all you need is to read the Error: statement – carefully. Then locate the code referenced by Line:. Incidentally, Source: reports a runtime error not a compilation error, this means you are looking not for a pure syntax problem, but a fault logic error.
