I am making a client database.

I have for example SHEET 1 (nice clean looking for ease of use) which draws data from SHEET 2 (rows and columns of raw data)

What i need to do is on SHEET 1 I need to be able to add the outcome of my call/add further details to it, and then copy and paste that to SHEET 2.

How do I do this?

(I have over 400 records)

If needs be I can post a dummy sheet
