Audit Trail in one Field that Appends data

[Jed69]

I am setting up a field that creates an audit trail of certain actions taken on the database. The problem I have is appending the information rather than overwriting it. Ideally when a new piece of information is entered (which is done with a calculation) it

1. Goes to the end of the current information in the field

2. Starts a new line and

3. Inserts the information.

The only think I can not do is number 1. I realise this is probably easy but I just can not see it. can anyone help.

You know how I said it is probably simple, well I just worked out how to do it. Simply start the calculation with what is in the field already. I am so dim at times.
