I always get an error message on pageInit saying "TypeError Cannot read properties of undefined (Reading 'getLineCount').

Any problem with it?

On `pageInit`, `context` does not have a `newRecord` property.  Line 9 should probably read
```var itemReceiptFromRa = context.currentRecord;```

Here’s the docs for the pageInit entry point: <https://system.na0.netsuite.com/app/help/helpcenter.nl?fid=section_4410597671.html>

Yes, I believe you need to use context.currentRecord instead
