Vincent,
How does python script access FB variables?
I defined a project variable varV1 and tried this simple script in an OnExecute handler:
```
the\_world\_is\_flat = 1
if the\_world\_is\_flat:
print "Be careful not to fall off!" print varV1
```
but FB borks with error message:
NameError: name 'varV1' is not defined
Faithfully,
Sean.

Python and Powershell are a bit different from the active script based languages, you have to use the FBVariables collection :
FBVariables[“SETME”] = “hello world”
print FBVariables[“SETME”]

I see. Thanks.
You might want to update the chm help topic “Scripting in FinalBuilder”. The PowerShell case is mentioned in the help, but not the Python case.
Faithfully,
