Find min 2 and max 2 cell values then highlight

I have searched, googled, and just can 't find the right code for this question, I hope someone can help me.

I want to identify the 2 minimum valued greater than 0.00% in rows with percentages only. Then identify the 2 maximum values greater than 0.00% in rows with percentages only. The sheet changes in size (rows and columns) each day. C4 Row 4 is a constant starting place if that is necessary. I have been tweaking this code all night, but no luck. I keep getting a highlighted yellow error in editor @ oRg.Find(What:=iMin, _
I also don't know what an oRg is, I am using 2001, that may be the problem.
Please help...

'   Sub FindMinValue()

    Dim oRg As Range, iMin As Variant
    Set oRg = Cells
    iMin = Application.Min(oRg)
    
    With oRg
    oRg.Find(What:=iMin, _
        After:=oRg.Range("A1"), _
        LookIn:=xlValues, _
        LookAt:=xlPart, _
        SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False _
        ).Select
    End With

        .PatternColorIndex = xlAutomatic
        .ThemeColor = xlThemeColorAccent3
        .TintAndShade = 0
        .PatternTintAndShade = 0
    End With
 
    'Displaying min value info
