I need a fourmal for this question for Microsoft excel.

Create a column called Credit. If the Score of the customer is less than 40, then give a Poor value in the Credit column. If the Score of the customer is equal to or higher than 40 but equal to or less than 70, then give an OK value. If the Score of the customer is higher than 70 but less than 90, then give a Good value. If the Score of the customer is equal to or higher than 90, then give an Excellent value. You must use a lookup function WITH an ARRAY Form for this column. Be sure that you implement the EXACT cutoff here using a range of scores with no more than 4 rows. No points will be given for using IF function.
