How to get 0 if my result is a negative number in one formula.

How to get 0 if my result is a negative number in one formula.

Hi, im new to formulas and zoho, i made one but i dont know how to implement one "if", tried several times and i got sintax errors.
This is the formula

${Capittala.No. Visitas cierre}-(${Capittala.VC1}+${Capittala.VC2}+${Capittala.VC3}+${Capittala.VC4})

It works, i get results but i can get negative numbers and my client doesn't want that
Zoho gave me this if:
If(${Loans.Decimal 2}>0,${Loans.Decimal 2},0)
And i dont know how or where i can put it, tried on the formula itself but it gave me error.
Any idea?
Thanks :)
