Referencing Multiple Sheets with large sets of Data - vba

Question

I am fairly new to VBA and having some general obstacles with basic syntax. I am using the below code to trim leading spaces and color code an ActiveSheet I am currently working on.
I have another Worksheet called "Country" that I would like to apply the same logic to the current sheet I am using. I am also having difficulties using the most efficient code to find any cells with values of "AcctTotal" , " CurrTotal" and " BravoTotal" (there are about 14,000 rows of data). I am currently highlighting the whole spreadsheet and utilizing "UsedRange" to find these cells.
To sum it up:
I would like to trim leading spaces and color code any values of "AcctTotal" , " CurrTotal" and " BravoTotal" in two worksheets: "Currency" and "Country"
Sub ColorCodeCurrency()
Dim r As Range
For Each r In Selection
If r.Value = " AcctTotal" Then
r.Value = LTrim(r.Value)
Intersect(r.EntireRow, ActiveSheet.UsedRange).Interior.ColorIndex = 15
End If
Next r
Dim s As Range
For Each s In Selection
If s.Value = " CurrTotal" Then
s.Value = LTrim(s.Value)
Intersect(s.EntireRow, ActiveSheet.UsedRange).Interior.ColorIndex = 40
End If
Next s
Dim t As Range
For Each t In Selection
If t.Value = " BravoTotal" Then
t.Value = LTrim(t.Value)
Intersect(t.EntireRow, ActiveSheet.UsedRange).Interior.ColorIndex = 35
End If
Next t
End Sub

Answer 1

Most of the problem is that you're doing the same thing three times. The 'For Each' statement is going through every cell three times. If you joined it into
for each r in selection
if r.value ="AcctTotal" then
'do something
elseif r.value = "CurrTotal" then
'do something else
elseif r.value = "BravoTotal" then
'do the third thing
end if

Answer 2

In addition to what Maudise said, when you refer to your data, you can use syntax like:
Sheets("Country").Range("A1:E14000")
If it's possible to make changes to your source data, you may find it helpful to format it as a table for easy reference. Use the Name Manager to give the table a useful name. Then, you can say something like:
For Each r In Sheets("Country").Range("CountryTable")

Answer 3

You could try this way:
Public Sub ColorCode ()
Dim i As Integer, j As Integer, m As Integer, n As Integer
i = Range("A:A").End(xlDown).Row
j = Cells.End(xlToRight).Column
For m = 1 To i
For n = 1 To j
If Cells(m, n).Value < 50 Then
Cells(m, n).Interior.ColorIndex = 13
End If
Next n
Next m
End Sub
One solution is to call this code placed in a module into "This workbook" in "Private Sub Workbook_Open()".
