New to access need help with doing some basic math with fields set for currency.

[hjnash]

Hello, good day! I just installed access 2013, never used access before. I am playing with a stand alone database


where I have fields with currency for deposit, spent, and I need a field for the total. I can't find what I need to do
to tell the field (Balance) to do a math action or function. Need some direction please, Thanks!

Sum([deposit]) -Sum([spent])
