Minimum search which crashes when there are no values

[simmo]

Here is code which finds minimum values in certain columns, it works great,except when there are no values in some columns, can anyone suggest any modifications that would help.

' Sub FormatMinimum()
Range("C4:C120,E4:E120,G4:G120,I4:I120,K4:K120,L4:L120").Interior.ColorIndex = 0

Dim MinRange1 As Range, MinRange2 As Range, MinRange3 As Range, MinRange4 As Range, MaxRange5 As Range, MaxRange6 As Range

Dim MinVal1 As Long, MinVal2 As Long, MinVal3 As Long, MinVal4 As Long, MaxVal5 As Long, MaxVal6 As Long

Set MinRange1 = Range("N4:N120")
Set MinRange2 = Range("O4:O120")
Set MinRange3 = Range("P4:P120")
Set MinRange4 = Range("Q4:Q120")
Set MaxRange5 = Range("K4:K120")
Set MaxRange6 = Range("L4:L120")

MinVal1 = Application.WorksheetFunction.Min(MinRange1)
MinRange1.Find(What:=MinVal1, After:=Range("N4"), LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
MatchCase:=False).Offset(0, -11).Interior.ColorIndex = 44

MinVal2 = Application.WorksheetFunction.Min(MinRange2)
MinRange2.Find(What:=MinVal2, After:=Range("O4"), LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
MatchCase:=False).Offset(0, -10).Interior.ColorIndex = 44

MinVal3 = Application.WorksheetFunction.Min(MinRange3)
MinRange3.Find(What:=MinVal3, After:=Range("P4"), LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
MatchCase:=False).Offset(0, -9).Interior.ColorIndex = 44

Something like this:

Dim x As Range

MinVal1 = Application.WorksheetFunction.Min(MinRange1) 
Set x = MinRange1.Find(What:=MinVal1, After:=Range("N4"), LookIn:=xlValues, _ 
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _ 
MatchCase:=False)
If Not x Is Nothing Then
   x.Offset(0, -11).Interior.ColorIndex = 44
End If

Thanks for that piece of code Andrew, do i replace my "MinVal1" statement with the one you have written ? and then replace / edit MinVal2,MinVal3 and MinVal4. I dont mean to sound dumb, but I have lots to learn.

Replace:

MinVal1 = Application.WorksheetFunction.Min(MinRange1) 
MinRange1.Find(What:=MinVal1, After:=Range("N4"), LookIn:=xlValues, _ 
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _ 
MatchCase:=False).Offset(0, -11).Interior.ColorIndex = 44

with

MinVal1 = Application.WorksheetFunction.Min(MinRange1) 
Set x = MinRange1.Find(What:=MinVal1, After:=Range("N4"), LookIn:=xlValues, _ 
LookAt:=xlWhole, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _ 
MatchCase:=False)
If Not x Is Nothing Then
   x.Offset(0, -11).Interior.ColorIndex = 44
End If

and repeat for the other two blocks, changing variable and range references as necessary.

Dim x As Range

goes in once at the top.
