is this sentence correct? (please help someone)

[leekwanhoa]

'Take one copy of the form and original invoice for the Legal Fees file and send the originals to Alison Cook in Edinburgh'

or is it better to use:

'Take one copy of the form and invoice for the Legal Fees file and send the originals to Alison Cook in Edinburgh'

is the first sentence confusing? can you use a word as a noun and adjective in the same sentence?

please someone help me!!!

Welcome, leekwanhoa.

Leave a copy of the form and a copy of the original invoice in the Legal Fees file, and send the originals to Alison Cook in Edinburgh.

You could - but there's no need to - change the word "original" to, say, the client's invoice or our company's invoice.

All the best.
