How to fire an Excel macro from MSAccess?

I have an Excel spreadsheet that is always open. I want to use Visual Basic in MSAccess to execute an Excel macro based upon certain conditions in the MSAccess database. I can use Auto Open to run the macro from a closed Excel Spreadsheet from MSAccess by closing it and then opening the spreadsheet, but I can't find out how to fire the macro from MSAccess when the spreadsheet is already open. Appreciate any insights. Thanks.
