I am trying to assign a shortcut key to a macro in an add-in. I added the
following to ThisWorkbook

Private Sub Workbook_Open()
Application.OnKey "+^{R}", "Liquidity.LiquidityCollFormat"
Application.OnKey "^{R}", "Liquidity.LiquidityResize"
End Sub

but when I try to run it I get the message, The Macro c:\... cannot be found.

Where have I gone wrong?

Many thanks for any assistance.
