asked on # Excel 201 rounding creating a problem with my macro

I am trying to get the OilTotal cell to change based upon the entry in the OilQuantity cell. I’m sure this has to do with rounding. Can someone help debug my macro or make it easier to read/understand? See attached file.

Here's something I copied from the web. BTW, please don't forget to close this question.

One of the best methods for multiple conditions is the Select Case Statement. It does away with the need for multiple If Statements which can make Excel VBA code very hard to read and decipher. The Select Case Statement has a syntax of:

One of the best methods for multiple conditions is the Select Case Statement. It does away with the need for multiple If Statements which can make Excel VBA code very hard to read and decipher. The Select Case Statement has a syntax of:

```
Select Case < Expression to test>
Case
Do something
Case Else
Do something else
End Select
As you can see the Select Case Statement is very similar to the If Statement in that it will only perform some action if/when a condition is met. However, as you will learn, the Select Case is far more flexible. Let's look at the "Select Case" Statement in it's simplest form.
Sub TheSelectCase1()
Select Case Range("A1").Value
Case 100
Range("B1") = 50
End Select
End Sub
Now let us say you need to perform any one of 5 actions depending on the Value of Range A1. If so we could use;
Sub TheSelectCase2()
Select Case Range("A1").Value
Case 100
Range("B1").Value = 50
Case 150
Range("B1").Value = 40
Case 200
Range("B1").Value = 30
Case 350
Range("B1").Value = 20
Case 400
Range("B1").Value = 10
End Select
End Sub
This, in my opinion, is a far better structure and easier to read than an If Statement with multiple ElseIf Statements. If none of the above Conditions were met, nothing would occur, unless we use the optional Case Else Statement, like:
Sub TheSelectCase3()
Select Case Range("A1").Value
Case 100
Range("B1").Value = 50
Case 150
Range("B1").Value = 40
Case 200
Range("B1").Value = 30
Case 350
Range("B1").Value = 20
Case 400
Range("B1").Value = 10
Case Else
Range("B1").Value = 0
End Select
End Sub
So if the value of range A1 is NOT 100,150,200,350 or 400 then place a Value of 0 (zero) in Range B1.
Now while this demonstrates how we can check multiple conditions with the Select Case Statement, what if we want to perform some action if the Range A1 is equal to any one of the Values 100,150,200,350 or 400. If this is the case (no pun intended) we could use:
Sub TheSelectCase4()
Select Case Range("A1").Value
Case 100, 150, 200, 350, 400
Range("B1").Value = Range("A1").Value
Case Else
Range("B1").Value = 0
End Select
End Sub
Let's assume that you only want to perform some action if the range(s) you are checking are between 2 numbers. If this is the case (excuse the pun) then you could use:
Sub TheSelectCase5()
Select Case Range("A1").Value
Case 100 To 500
Range("B1").Value = Range("A1").Value
Case Else
Range("B1").Value = 0
End Select
End Sub
In this instance, if the range A1 contains a number => 100 and =< 500 then cell A1 value will be placed into cell B1.
Now, what about if we needed to check if cell A1 was not only between 100 and 500 but also between 700 and 1000, 1500 and 2000? No problem, with the Select Case you would simply use:
Sub TheSelectCase6()
Select Case Range("A1").Value
Case 100 To 500, 700 To 1000, 1500 To 2000
Range("B1").Value = Range("A1").Value
Case Else
Range("B1").Value = 0
End Select
End Sub
In other words if cell A1 contains a number (eg 600) that does not meet the Case criteria, B1 will equal 0. By-the-way, the limit using a Select Case like this is far from 3 criteria! You can also mix and match the criteria you use in a Select Case Statement, so if you wanted to include some text and/or specific numbers you could use:
Sub TheSelectCase()
Select Case Range("A1").Value
Case 100 To 500, 652, 700 To 1000, 1233, 1500 To 2000, "dog", "cat"
Range("B1").Value = Range("A1").Value
Case Else
Range("B1").Value = 0
End Select
End Sub
Select Case Knows its Alphabet
The last benefit we will look at with the Select Case Statement is how we can use it on text and determine if it lies between other text in an alphabetical sense
Sub TheSelectCase7()
Select Case Range("A1").Text
Case "aardvark" To "elephant"
Range("B1").Value = "it's between"
Case Else
Range("B1").Value = "it's not between"
End Select
End Sub
```

Thank you for the lesson and documentation.

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Here's another way to use Select case that I find useful.

```
Select Case True
Case Range("A1") = 50
MsgBox "OK"
Case Range("B1") = Empty
MsgBox "Please don't forget to close the question"
Case ActiveSheet.UsedRange.Rows.Count > 10000
MsgBox "too many"
End Select
```
