VBA Compare 2 columns and Return the difference in anoth column

[decadence]

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

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

Example

Rng1 Column	Rng2 Column	Some Column	Other Column	xRng Column
60	300
100	0
0.001	0
20	20

<tbody>
</tbody>

To

Rng1 Column	Rng2 Column	Some Column	Other Column	xRng Column
60	300			240 (Green)
100	0			100 (Red)
20	20			0 (Blue)

Sorted this now, colors changed from previous post. Code below in case others have the same problem
