Trying to assign formula with dynamic range to a cell

Trying to use the following assignment. Can not use relative referencing, that I know of, because the last column can change.

Dim LastCol as long

'Comment: LastCol = 90

This syntax:
Range("E2").Formula = "= "Average(" & Range (Cells(2,7), Cells(2, LastCol - 2 )) & ")" "
won't compile, says "Syntax error"

This syntax:
Range("E2").Formula = "= ""Average("" & Range (Cells(2,7), Cells(2, LastCol - 2 )) & "")"" "
just copies the text into the cell. The formula does not work.

If I am correct in my understanding of what you are trying to achieve, I suggest that you use this statement:

Range("E2").Formula = "=Average(" & Range(Cells(2, 7), Cells(2, LastCol - 2)).Address & ")"

You need to use the .Address property of the range object when building your formula:
Range("E2").Formula = "= Average(" & Range (Cells(2,7), Cells(2, LastCol - 2 )).Address & ")"

Note that I deleted two doublequotes as well.

Thanks fanpages. That almost works. It generates a working formula in the cell but the location references are absolute references, =AVERAGE($G$2:$CP$2).  I want to copy the formula down a column so need relative addresses. =AVERAGE(G2:CP2)

Range("E2").Formula = "= Average(" & Range (Cells(2,7), Cells(2, LastCol - 2 )).Address(false,false) & ")"

The Address property of the range lets you specify whether the row and column references are absolute or relative.

Please give the points on this thread to fanpages, because he posted the solution first. I'm just trying to provide the reasons why the changes are needed.

Thanks to both fanpages and byundt for the solution.

byundt I had to give you some points for being first with the complete solution. I have no doubt that fanpages would have arrived at the same solution but speedy response also provides a premium.

At 2:15am (UK time), when I posted the comment, was the best time to ask me that.

I slept (a little) since.
