Thanks Duke Carey and andy62. Both of the solutions work perfectly.

One way is to use the INDIRECT function, which ignores inserts, copy/pastes,
etc:

=SUM(INDIRECT("A2:A10"))

I would like to do a sum or count formula between a specific range for column
totals. If I use for eg sum(A2:A10) or Sum(A2:$A$10) they are both affected
when a row is inserted and the 10 is now changed to 11.
Is there a formula that can be used so in A1 I have my start row value as 2
and B1 my end row value as 10, then build a Sum or Count formula as:
=Sum or =Count(A&Value(A1):A&Value(B1)) ??
