This blog explains the lesser known but better Excel VBA InputBox function

Posted by Andy Brown on 17 December 2015

There are two ways you can display an input box using Excel macros: the standard VBA InputBox function, or the much better (but lesser known, at least by this blog's author) Application.InputBox function.

Firstly please let me introduce myself, I'm Charlie, I'm new to coding and I have been given a task. The task is to create code to generate discrete part descriptions for every part number our system can generate. I have attached the code that was written to generate the part numbers, I have also attached the code that I am trying to use to generate the descriptions which has compile error type mismatch occurring.

I would very much like to understand the original code and then create new rather than someone writing the code and just accepting that it works, as has happened before, hence the current situation! My first major hurdle is understanding the "i" in for example:

Dim i1 As Long

If Cells(i2, 2) Mod 2 <> 0 And Cells(i4, 4)

and

Next i5

Amongst other areas of the code.

Sub series325()
Dim a As Long
Dim b As Long
Dim c As Long
Dim d As Long
Dim e As Long
Dim i1 As Long
Dim i2 As Long
Dim i3 As Long
Dim i4 As Long
Dim i5 As Long
Dim counter As Long

counter = 1

a = Range("A1").End(xlDown).Row
b = Range("B1").End(xlDown).Row
c = Range("C1").End(xlDown).Row
d = Range("D1").End(xlDown).Row
e = Range("E1").End(xlDown).Row

For i1 = 2 To a
For i2 = 2 To b
For i3 = 2 To c
For i4 = 2 To d
For i5 = 2 To e
If Cells(i2, 2) Mod 2 <> 0 And Cells(i4, 4) Mod 2 = 0 Then GoTo Nexti
If Cells(i2, 2) Mod 2 <> 0 And Cells(i4, 4) = "-2" Then GoTo Nexti
If Cells(i2, 2) > 61 And Cells(i4, 4) = "-1" Then GoTo Nexti
Cells(counter, 10) = Cells(i1, 1) & Cells(i2, 2) & Cells(i3, 3) & Cells(i4, 4) & Cells(i5, 5)
counter = counter + 1
Nexti:
Next i5
Next i4
Next i3
Next i2
Next i1
End Sub

I would like to apply the same method to the descriptions. I was hoping the code below might work, sadly it didn't.

Sub series325PartDescriptionTest()
Dim a As String
Dim b As Long
Dim c As String
Dim d As String
Dim e As String
Dim f As String
Dim g As String
Dim i1 As String
Dim i2 As Long
Dim i3 As String
Dim i4 As String
Dim i5 As String
Dim i6 As String
Dim i7 As String
Dim counter As String

counter = 1

a = Range("A1").End(xlDown).Row
b = Range("B1").End(xlDown).Row
c = Range("C1").End(xlDown).Row
d = Range("D1").End(xlDown).Row
e = Range("E1").End(xlDown).Row
f = Range("F1").End(xlDown).Row
g = Range("G1").End(xlDown).Row

For i1 = 2 To a
For i2 = 2 To b
For i3 = 2 To c
For i4 = 2 To d
For i5 = 2 To e
For i6 = 2 To f
For i7 = 2 To g
If Cells(i2, 2) Mod 2 <> 0 And Cells(i5, 5) Mod 2 = 0 Then GoTo Nexti
If Cells(i2, 2) Mod 2 <> 0 And Cells(i5, 5) = "Double Row formation. " Then GoTo Nexti
Cells(counter, 10) = Cells(i1, 1) & Cells(i2, 2) & Cells(i3, 3) & Cells(i4, 4) & Cells(i5, 5) & Cells(i6, 6) & Cells(i7, 7)
counter = counter + 1
Nexti:
Next i7
Next i6
Next i5
Next i4
Next i3
Next i2
Next i1
End Sub

I am struggling to add the spreadsheets for reference, the formatting falls apart when I use copy & paste.

Hi Charlie, thanks for your question! It's a tricky one to answer in a simple comment like this one because, as you say, you're new to programming. Fortunately, we've created both written and video tutorials on VBA that will help you to understand all of the elements that go into making up the procedure you're trying to create.

This page lists the written articles that are part of our main Excel VBA tutorial. We've written plenty of other articles on more esoteric aspects of the language but the articles in that tutorial will give the core skills you need.

If you'd prefer to watch rather than read, you can see a list of our Excel VBA videos here. The main ones you'll need in order to understand the code you've posted are the videos on Selecting Cells, Variables in VBA, If Statements in VBA and For Next Loops.

I hope that helps!
