[support] views and calculated fields

[Lluís]

I have a view with two fields (A and B), both of them numeric. I want
to make a filter to show nodes when A + B = 0

How can I make this? I suppose I should add A and B as hidden fields
and then there should be a calculated field anywhere allowing to
add(), concatenate(), .... But I have been unable to find this module.

Thanks
