I need to implement a more than 7 IF nested Statements in a Master Excel sheet I am creating. It is a Tolerance Table that I need to put several times across the sheet and across the book. I know it can be done in VBA but I am not an expert in VBA.

Of course I tried to write the whole formula in EXCEL although I know it was not going to be accepted.

Average % intervals________Tolerance
99 and 2_____________________ 2
97-98 and 3-4_________________3
94-96 and 5-7_________________4
91-93 and 8-10________________5
87-90 and 11-14_______________6
82-86 and 15-19_______________7
76-81 and 20-25_______________8
70-75 and 26-31_______________9
60-69 and 32-41______________10
51-59 and 42-50______________11

=IF(CELL=2,"2",IF(CELL=4,"3",IF(CELL=7,"4",IF(CELL =10,"5",IF(CELL=14,"6",IF(CELL=19,"7",IF(CELL=25," 8",IF(CELL=31,"9",IF(CELL=41,"10",IF(CELL=59,"11", IF(CELL=69,"10",IF(CELL=75,"9",IF(CELL=81,"8",IF(C ELL=86,"7",IF(CELL=90,"6",IF(CELL=93,"5",IF(CELL=9 6,"4",IF(CELL=98,"3",IF(CELL=99,"2"))))))))))))))) ))))
