Okay here’s my sample code :

[code]def read\_parameter():  
do something here

def parse\_parameter():  
read\_parameter()[/code]

and on a button I am calling `parse_parameter()
`But its giving me this error.

```auto
NameError: global name 'read_parameter' is not defined
```

You are using legacy scoping. You must use standard scoping to call functions this way.

You can find out more about standard/legacy scoping here: [perfectabstractions.com/blog … rd-scoping](http://www.perfectabstractions.com/blog/new-scripting-features-in-ignition-77-part-1#standard-scoping)

Best,
