Variables and Constants in Excel Visual Basic
Part four of an eight-part series of blogs

This blog explains the nuts and bolts of Excel VBA variables, including how to declare them, how to set their scope and all sorts of other tips and tricks. The blog also covers constants in Excel macros.

Using Variables (Assigning and Retrieving Values)

First, a quick reminder of what we're trying to do with our macro:

Votes to be copied Worksheet of results
We're trying to copy the vote ... ... into the results sheet

There are only two basic commands with a variable - you can either assign a value to it, or read a value from it:

'put the current cell value into the variable HeroName

HeroName = ActiveCell.Value

'retrieve value from variable HeroName and store it in the current cell

ActiveCell.Value = HeroName

Bearing this in mind, let's have a look at our macro (it's listed in full at the bottom of this page).  First, we declare the variables we're going to use:

Sub RecordVote()

'the name of each superhero

Dim HeroName As String

'the rating assigned to them

Dim HeroRating As Long

The next thing to do is to find out the current hero's name and rating, and store these in variables:

'go to the votes sheet and get the value of the superhero, and their rating

Worksheets("Votes").Select

HeroName = Range("C4").Value

HeroRating = Range("C6").Value

Now we need to go the results sheet, and go down to the cell where the votes will be recorded:

'go to top of results

Worksheets("Results").Select

Range("B4").Select

'go to first blank cell

ActiveCell.End(xlDown).Select

ActiveCell.Offset(1, 0).Select

Now it's simply a case of transferring the information we've stored in the two variables into the worksheet:

'write variable values into this blank row

ActiveCell.Value = HeroName

ActiveCell.Offset(0, 1).Value = HeroRating

Finally (and this bit has nothing to do with variables), I've put two slightly complicated lines to copy the formatting down from the row above:

'copy formats from cell above (included here just to make macro complete)

Range(ActiveCell.Offset(-1, 0), ActiveCell.Offset(-1, 1)).Copy

ActiveCell.PasteSpecial xlPasteFormats

Application.CutCopyMode = False

Here's the full code, if you want to try it out:

Sub RecordVote()

'the name of each superhero

Dim HeroName As String

'the rating assigned to them

Dim HeroRating As Long

'go to the votes sheet and get the value of the superhero, and their rating

Worksheets("Votes").Select

HeroName = Range("C4").Value

HeroRating = Range("C6").Value

'go to top of results

Worksheets("Results").Select

Range("B4").Select

'go to first blank cell

ActiveCell.End(xlDown).Select

ActiveCell.Offset(1, 0).Select

'write variable values into this blank row

ActiveCell.Value = HeroName

ActiveCell.Offset(0, 1).Value = HeroRating

'copy formats from cell above (included here just to make macro complete)

Range(ActiveCell.Offset(-1, 0), ActiveCell.Offset(-1, 1)).Copy

ActiveCell.PasteSpecial xlPasteFormats

Application.CutCopyMode = False

End Sub

Variables are that simple!
