WD21 - How to negate a value when defining a Query

Hello All,

I trust this finds you all well.

I am building two queries to be used in a join. I would like to query data from two different months. For one month I want the values to be positive (+ve) and the other month Negative (-ve). I want to build a report out of the 'joined queries' such that query1.value+query2.value will give me the net of the two [ query1.value(+ve) + query2.value (-ve) ]=Net.

How do I get the queryvalue "negated" in the query builder?

Thanks in advance.

Sam
