Ok .. looks good. Thanks for the answers - helps me better understand the intent.

The Denomination had me confused ... when looking at the Sheet information there are
traditional denoms and also 'books', etc. Wasn't certain which direction it was supposed to go. Now I understand 'traditional denom'.

My personal preference would be to have the Calcs sheet hidden at all times to minimize the possibility of someone editing the data. Could mess things up otherwise.

Do you have any other questions we can assist with ?
