Hope anyone here could help me out with this.

I have solved an algorithm which I was asked to do by my tutor,but apparently it's not what he's looking for.He's asking for steps at the beginning of the algorithm to show how I got the data from the user, and steps at the end outputting the relevant values. These are important steps in the algorithm.

this is the algorithm I wrote:

If CustomerType = "Library" Or CustomerType = "School" Or CustomerType = "Educational Institutions" Then

If Qty >= 50 Then

Discount = 30

ElseIf Qty >= 25 And Qty <= 49 Then

Discount = 20

ElseIf Qty >= 15 And Qty <= 24 Then

Discount = 15

ElseIf Qty >= 5 And Qty <= 14 Then

Discount = 10

ElseIf Qty < 5 And Qty > 0 Then

Discount = 5

Else: Discount = 0

If CustomerType = "Individuals" Then

If Qty >= 25 Then

Discount = 25

ElseIf Qty <= 24 And Qty >= 5 Then

Discount = 15

Else: Discount = 0

If CustomerType = " " Then

Discount = 0
