Add text to formula result

[Mr_Adams]

I use this formula to give me new invoices numbers each time the worksheet is opened.

=MAX('\\Ice\Fin_Data\Invoices\2003\[Finance Invoice Ledger 2003.xls]Finance Invoice Ledger 2003'!$A:$A)+1

How can I put text in front of the result and insure the numeric value is 5 didgits.

Example:
The formula result is 560.
But I want the result to be FIN-00560.

Thank you for any help.
