Sorry for asking these maybe " dumb " questions for someone but I'm still a noob..
So if anyone could teach/explain me how can i make somehow a table for example:
money / day ........ ( here is a box )
costs / day .......... ( here is a box)
total ..... (here is a box)
and i must subtract the costs from the money and show somewhere.
how can i do this corectly ?
