Need Desperate help on my loop. Keep getting same error....

Hello,

I need my macros to search for the word "Cancel" in columns "T". Once found, I need the macros to make that entire row a certain pattern ( .Pattern = xlGray16)

There will be other wording in these cells that contain "Cancel" or "Cancelled".

A compile error keeps occurring. It says "Ambiguous name detected: FormatCell"..

I'm confused with it..... any suggestions?

Sub DoCancelCells()

    Dim strSearchString As String
    Dim wksSheet As Worksheet
    Dim rngSearchRange As Range
    Dim intSearchCount As Integer
   
    Application.ScreenUpdating = False
   
    'String to search for.
    strSearchString = "cancel"
    intSearchCount = 0
   
    For Each wksSheet In ActiveWorkbook.Sheets
   
    wksSheet.Select
   
        Set rngSearchRange = Range("T1:T" & Range("T" & Rows.Count).End(xlUp).Row)
       
            For Each cell In rngSearchRange
           
                If cell.Value = strSearchString Then
               
                    intSearchCount = intSearchCount + 1
                   
                    Call FormatCell(cell.Address)
               
                End If
               
            Next cell
           
            Set rngSearchRange = Nothing
   
    Next wksSheet
   
   
    Application.ScreenUpdating = True
   
End Sub
Sub FormatCell(strCellAddress As String)

    With Range(strCellAddress).EntireRow.Interior
        .Pattern = xlGray16
        .PatternColorIndex = xlAutomatic
        .ColorIndex = xlAutomatic
        .TintAndShade = 0
        .PatternTintAndShade = 0
    End With

Thank you in advance for your help.
