We have a query that calculates the cost total of three different types of costs between three different parameters. I now need to run a query that prompts the user for the days currency conversion rate to create a new report. I don't want to permanently convert the original fields, it is purely a monthly report where when the report is run is shows both British £ and USD. I get the feeling that it should be simple but I can't see it at present and have no other query that runs this kind of report to crib from. I've been TOLD this should be fun!
