Do you have better solution?

Maybe. Your use of ADDRESS doesn't seem to be based on any specific
condition other than to find the end of the range:

ADDRESS(C14+1
C14=COUNTA(C2:C11) = 9

But you're manually finding that end of range by using: =COUNTA(C2:C11)

If you explained what you're wanting to do we might be able to come up with
a better solution. Are you wanting to use a dynamic range based on C2:Cn ?

=SUM(C2:INDEX(C2:C65536,COUNTA(C2:C65536)))

Assumes no empty cells within the range.

Not sure why you are using ADDRESS though,

but try this:

C20=SUM(INDIRECT(ADDRESS(ROW(C2),COLUMN(C2),
1,TRUE)&":"&(ADDRESS(C14+1,COLUMN(C2),1,)))

Hope this helps.

It works when I put them separately in different cells and use
concatenate
and indirect to combine them as follows:

C14=COUNTA(C2:C11) = 9
C16=ADDRESS(ROW(C2),COLUMN(C2),1,TRUE) = the result is $C$2
C17=ADDRESS(C14+1,COLUMN(C2),1,) = the result is $C$10
C18=CONCATENATE(C16,":",C17)
C19=SUM(INDIRECT(C18)) = Gives the result of SUM(C2:C11)

When I try to substitute above functions in one cell as follows:
C20=SUM(ADDRESS(ROW(C2),COLUMN(C2),1,TRUE):ADDRESS (C14+1,COLUMN(C2),1,))
It says my formula has errors. What is the error and how can I solve
it?
Isnt it allowed to use combination of functions for references?
