Excel suddenly won't allow me to delete a worksheet

Excel suddenly won't allow me to delete a worksheet.  I have tried both ways - right click on tab and delete up top.  I don't get errors.  It just doesn't work....

@asactuary Make sure you have at least one worksheet left as you can't delete a sheet when you only have one.

@Riny_van_Eekelen  - thanks.  Yeah - there are plenty of sheets - just trying to delete 1 of many.
