Cell D11 formula: HLOOKUP( B11 , C2:H7 , 5 ) determines the lowest cost to send a 13.7 pound package
Cell E11 formula: HLOOKUP( B11 , C2:H7 , 6 ) determines the lowest cost mode to send a 13.7 pound package
It is often handy to specify the table by an absolute address ($C$2:$H$7) instead of a simple relative address (C2:H7). This greatly simplifies copying vlookup formulas to other cells in your spreadsheet.
