1- Lookup Functions
2- Counting Functions
Lookup Functions: Excel
How does it work?
1- Look up for the values that exceeds it and it returns to the previous one.
It doesn't have to be in ascending order
RELATIVE B2, ABSOLUTE $D$11:$E$15, COLUMN # 2
No absolute: without the $
What happens if I remove them $ ?
When you define a formula makes sure to test it with different values, look up
table has moved on one.
What happens: Does 25 exceeds one? Yes
We are outside the lookup table!
You should know an ERROR MSG will appear
What happens if everything is absolute (Meaning that we add the $ to
everything)?
I will always refer to B2; all my decision will be based on the first company.
= VLOOKUP( B2, $C$22:$E$15, 1)
1: WHERE THE LOOKUP TABLE IS GOING TO RETRIEVE THE VALUE FROM.
