if(and formula please

[d0wnt0wn]

how do i change this formula to an if(and statement so i do not get an error like div or name

=IF(C18<>0,(C18*G18)/C15,"")

lets say if c18 and c15 are <>0

=IF(N(C18)*N(C15),(C18*G18)/C15,"")

im not good with formulas so I made it they wrong way but it does work:

=IF(((C15<>0)+ (C18<>0))=2,5,0)

 

[d0wnt0wn]

neither worked sorry
