Hi I am trying to compare cells in 2 columns and return the value in the 3rd column on the same Row.

This is what I have so far, which is the Ranges I need to use, and have several criteria
Compare each cell between Rng1 and Rng2 and if return the value in the xRng Column if:

-the cell Value in Rng1 is below number 1 then hide that row

-the same number between Rng1 and Rng2 then returned value in xRng column as "0" and turn xRng cell Blue

-the difference is greater in Rng1 than Rng then return the difference and turn xRng cell Red

-the difference is Smaller in Rng1 than Rng then return the difference and turn xRng cell Green


Can someone help with this please

Code:
Option Explicit
Public Fnd As Range, Rng1 As Range, Rng2 As Range, xRng As Range, xVal1 As Range, xVal2 As Range, xVal3 As Range

Sub Total()
     If Range("A1").End(xlToRight) = "Total" Then Exit Sub
     Range("A1").End(xlToRight).Offset(, 1) = "Total"
     Set Rng1 = RngReq
     Set Rng2 = RngIss
     Set xRng = RngTotal
     For Each xVal1 in Rng1
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Compare Columns and Return value
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
     Next xVal1
End Sub

Function RngReq() As Range
    Set Fnd = ActiveSheet.Columns.Find(What:="RequiredQty", LookIn:=xlValues, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext)
        If Not Fnd Is Nothing Then
            Set RngReq = Range(Fnd.Offset(1), Cells(Rows.count, Fnd.Column).End(xlUp))
        End If
End Function
Function RngIss() As Range
    Set Fnd = ActiveSheet.Columns.Find(What:="IssuedQty", LookIn:=xlValues, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext)
        If Not Fnd Is Nothing Then
            Set RngIss = Range(Fnd.Offset(1), Cells(Rows.count, Fnd.Column).End(xlUp))
        End If
End Function
Function RngTotal() As Range
    Set Fnd = ActiveSheet.Columns.Find(What:="Total", LookIn:=xlValues, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext)
        If Not Fnd Is Nothing Then
            Set RngTotal = Range(Fnd.Offset(1), Cells(Rows.count, Fnd.Column).End(xlUp))
        End If
End Function
