Derek/Bryan:
I currently use Libre Office to use BW, and just downloaded the link to the reference sheet. It does not give an option to open it with a program other than Excel which I do not have loaded on my laptop. Help the computer slow learner figure out how to open it without excel if its possible please
-Run 'Calc'
-Choose File/Open from the menu
-Navigate to where you saved the reference sheet
-Select it, and click 'Open'
That's should open it for you. If you don't want to do this every time then you can associate xlsx files with Calc, or you can do a 'Save as...' on the reference sheet and change the file type to "ODF Spredsheet (.ods)"
