subtotal not working

[squiggy]

I want to subtotal columns and I cannot do it. I had the ability to subtotal
last month now it does not work. Have I unknowingly switched off this
ability, if so, how do I get it back. Should I reinstall my software, I hope
that this is not the solution.

Thanks in advance.
