[RESOLVED] Create excel formula referring to "column numbers"

[A-D-D-F_Toxic]

I am trying to use Visual Basic 6 to create a formula in a cell, but the formula refers to cells that are stored in variables as a column number and a row number.
For example, let's say I wanted to create a formula
=SUM(C6: D12) [There should be no space between the colon and the D, but it was creating a smiley where it shouldn't have!]
The problem is: my program only knows these cells by 4 integers: Row 6(intRowOne), Column 3(intColOne), Row 12(intRowTwo), and Column 4(intColTwo). Is there any way I can create this formula only knowing the names of the variables?
I have tried:

oXLSheet.Cells(49,3).Formula = "=SUM(" & oXLSheet.Cells(intRowOne, intColOne) & ":" & oXLSheet.Cells(intRowTwo, intColTwo) & ")"

I have also tried:

oXLSheet.Cells(49,3).Formula = "=SUM(" & oXLSheet.Range(oXLSheet.Cells(intRowOne, intColOne), oXLSheet.Cells(intRowTwo, intColTwo)) & ")"

But got no luck. Any other ideas? Thanks.

I just found the solution by adding "Address" to each cell:

oXLSheet.Cells(49,3).Formula = "=SUM(" & oXLSheet.Cells(intRowOne, intColOne).Address & ":" & oXLSheet.Cells(intRowTwo, intColTwo).Address & ")"

Although using this method, when I looked in Excel, it said "=SUM($C$6:$D$12)" and I wasn't expecting the dollars signs, but it still seems to work fine.
