Find If Value Exists on other Worksheet (Excel)

Question

I have a macro tied to a button click event on my Excel worksheet. When this event fires, I need to see if the value on my worksheet FeedSampleForm Range("A5:B5").Value exists anywhere in column B of my other worksheet FeedSamples.

Can anyone assist me with this? I'm barely a user when it comes to Excel, and this is my first time "Developing" with it.

EDIT:

Current Code below. This is for different save procedures depending on if saving a new record or saving after editing a previously created record.

For Sample Data, say I'm looking for "FeedSampleForm".Range("A5:B5").Value which is "SR0238", I need to see if "SR0238" exists in column B on "FeedSamples" worksheet, currently containing "SR0237" - "SR0252". If it doesn't exist, I can use same code as my Add Record functionality, but if it does, I have to write to that exact row when saving.

    If modeAdd = True Then
    'Labeler Reg. No.
    Worksheets("FeedSamples").Range("A1").End(xlDown).Offset(1, 0).value = Range("L3:M3").value

A very easy way is to declare the range that you want to search in and the value that you want to find.

Sub findValue()

    Dim xlRange As Range
    Dim xlCell As Range
    Dim xlSheet As Worksheet
    Dim valueToFind

    valueToFind = "MyValue"
    Set xlSheet = ActiveWorkbook.Worksheets("Sheet2")
    Set xlRange = xlSheet.Range("B1:B10")

    For Each xlCell In xlRange
        If xlCell.Value = valueToFind Then
            'Do Something
        End If
    Next xlCell

End Sub

I'm assuming that your range of ("A5:B5") is a merged cell because you indicated that it contained a single value. Merged cells can just be referenced by the "top left" cell within the merge (or at least that's how I think of it). So your merged range of ("A5:B5") can be referred to as just ("A5"). Anyway, here is a modified version of the method above that is more suited for your needs.

Sub findValue(ByVal valueToFind As String)

    Dim xlRange As Range
    Dim xlCell As Range
    Dim xlFormSheet As Worksheet
    Dim xlSamplesSheet As Worksheet
    Dim iLastRow As Integer
    Dim iRow As Integer
    Dim bFound As Boolean

    bFound = False
    Set xlFormSheet = ActiveWorkbook.Worksheets("FeedSampleForm")
    Set xlSamplesSheet = ActiveWorkbook.Worksheets("FeedSamples")

    iLastRow = xlSamplesSheet.Range("B1").End(xlDown).Row

    Set xlRange = xlsamplesheet.Range("B1:B" & iLastRow)

    For Each xlCell In xlRange
        If xlCell.value = valueToFind Then
            bFound = True '<-- The value was found
            iRow = xlCell.Row '<-- Here is the row that the value was found on
        End If

        If bFound Then Exit For '<-- Optional: Exit the for loop once the value is found the first time
    Next xlCell

End Sub
