Excel VBA Variable for R or C in an equation

below is a VBA formula for subtotalling filtered data and  which works fine if I define the column number as a given number  in in the section of code to the right
However I would like to define the column number as a variable ie Col Number 2 or Column Number 6 etc
Have seen some suggestions how this might work but doesnt seem to like the formula I am using
I know what I have put in is wrong but am trying to figure out the correct if possible version

Sub Analysis_Testdev()
 Dim ColNumberx As Integer
 ColNumberx = 2

    Application.CutCopyMode = False
    ActiveCell.FormulaR1C1 = _
    ' my problem is getting this bit of the above equation to work in that I want the Column Number to be a variable ColNumberx and i cant seem to get it to work
       '   --('WsheetA'![R49C&ColNumberx]:[R20000C&ColNumberx]='WsheetA'!RC[-1])),"""")"
       ' the aim is to create a valid formula in B10 based on whatever column I choose and then copy it to cells B10:B29 but I cant get the column number based on a variable right
End Sub

pls try
    ActiveCell.FormulaR1C1 = _
        "=IF('123WsheetA'!RC[-1]>-.1,SUMPRODUCT(SUBTOTAL(109,OFFSET('123WsheetA'!R48C5,ROW('WsheetA'!R49C5:R20000C5)-ROW('WsheetA'!R48C5),,1)),--('WsheetA'![R49C&ColNumberx]:[R20000C" & ColNumberx & "]='WsheetA'!RC[-1])),"""")"

Short answer is No but your response seems to have two different treatments of the variable
-('WsheetA'![R49C&ColNumberx]:[R20000C" & ColNumberx & "] = !WsheetA'!RC[-1])

ie ![R49C&ColNumberx] and then  [R20000C" & ColNumberx & "]

was that intentional  

Thanks Paul

You need to concatenate the column number in your formula (notice the additional quotes):
ActiveCell.FormulaR1C1 = _
         "=IF('123WsheetA'!RC[-1]>-.1,SUMPRODUCT(SUBTOTAL(109,OFFSET('123WsheetA'!R48C5,ROW('WsheetA'!R49C5:R20000C5)-ROW('WsheetA'!R48C5),,1)),--('WsheetA'![R49C" & ColNumberx & "]:[R20000C" & ColNumberx & "]='WsheetA'!RC[-1])),"""")"

Additional notes:
- Never use objects such as ActiveWorkbook, ActiveSheet, ActiveShape, Selection, Range (alone) as their value depend on user action, and are by nature chaotic.
As a developper, you don't want to use chaotic objects.
Prefer referencing directly and precisely the objects you need.
- Avoid selecting ranges, it is slow as hell.

Your code can easily be replaced by:
Sub Analysis_Testdev()
  Dim ColNumberx As Integer
  Dim ws as Excel.Worksheet
  Dim rng as Excel.Range

  ColNumberx = 2
  Set ws = ThisWorkbook.WorkSheets("WsheetA")
  Set rng = Range("B10")
  Application.CutCopyMode = False

  rng.FormulaR1C1 =  '// your formula here

   Set rng = ws.Range("B10")
   rng.Copy ws.range(""B10:B29")

It should be like this...
ActiveCell.FormulaR1C1 = _
    "=IF('123WsheetA'!RC[-1]>-.1,SUMPRODUCT(SUBTOTAL(109,OFFSET('123WsheetA'!R48C5,ROW('WsheetA'!R49C5:R20000C5)-ROW('WsheetA'!R48C5),,1)),--('WsheetA'![R49C" & ColNumberx & "]:[R20000C" & ColNumberx & "]='WsheetA'!RC[-1])),"""")"

Thanks very much to everybody for your suggestions. Particularly liked Fabrice's elegant work  .
Strangely none of the solutions quite worked in this particular case but pointed me in the right direction
It turned out I had two problems
1 I was seeking to use a column number ( say column 10 , 11, 12 etc) as a variable
2 because I was starting in column B to get the formula to work I needed to deduct the column number (B being column 2) from the original variable ColNumberx to create a second variable ColNumberxb =Colnumberx-2
Similarly if I am using C I was i would have a variable ColNumberxc = ColNumber-3
As I was only using about 10 columns it was no problem to define and use the 10 variables which in turn made creation of new VBA's much easier and faster
For some strange reason my square bracket worked in a slightly different place than suggested

ActiveCell.FormulaR1C1 = _
        "=IF('WsheetA'!RC[-1]>-.1,SUMPRODUCT(SUBTOTAL(109,OFFSET('WsheetA'!R48C5,ROW('WsheetA'!R49C5:R20000C5)-ROW('WsheetA'!R48C5),,1)),--('WsheetA'!R49C[" & ColNumberxb & "]:R20000C[" & ColNumberxb & "]='WsheetA'!RC[-1])),"""")"
