You're not assigning an amount to monthlySales before using it in the calculation.

Perhaps you mean to use those:

Select Case salesmanCode
  CASE 1
    monthlySales = 500
  ....
End Select

SalesPersonCommission = CInt(0.01 * monthlySales + 1000)

Depending on what exactly you're trying to do, you may want to surround part of your calculation in parentheses to indicate clearly what order you want the calculations to occur. The first calculation below gives a different result than the second:

SalesPersonCommission = CInt(0.01 * (monthlySales + 1000))
SalesPersonCommission = CInt((0.01 * monthlySales) + 1000)

The second is what you want.

It looks like you're forgetting to set monthlySales.

If you set it to 500 you get the results you say you're expecting.
