Heres my code so far:

Sub DetermineinterestIf()

Dim loan As Variant

Dim interest As Double

Do

loan = InputBox("Enter your desired loan amount, from 1 dollar to 5 million dollars.")

Loop Until IsNumeric(loan)

If loan < 1000000 Then interest = ".08"

If loan > 4000000 Then interest = ".11"

If 1000000 < loan < 4000000 Then interest = ".10"

MsgBox ("The loan amount was " & loan & " with an interest rate of " & interest & ".")

End Sub

Any ideas where I have gone wrong?

**Steve**, Friday, June 28, 2013 at 4:29pmFirst off, why use strings to specify a numeric (Double) value for interest?

I learned VBA a while ago, but I think that

If 1000000 < loan < 4000000 Then interest = .10

is invalid syntax. Try

If (1000000 < loan) and (loan < 4000000) Then interest = .10

Or, you might try

interest = 0.10

If loan < 1000000 Then interest = .08

If loan > 4000000 Then interest = .11

That is, assume the interest will be .10, and only change it if the loan amount is too big or too small

Or, if you find that you have to do other stuff depending on the interest rate, you could go whole-hog and say

If loan < 1000000 Then

interest = .08

do 8% stuff

Else If loan > 4000000 Then

interest = .11

do 11% stuff

Else

interest = .10

do 10% stuff

End If
