Excel "Too many arguments in formula Issue" for a schedual worksheet

I'm having some issues with the following formula:

=IF(COUNTA(B10:U10)>=8,COUNTA(B10:U10)-1,IF(AND(COUNTA(B10:U10)<8,COUNTA(B10:U10)>0),COUNTA(B10:U10)-0.5,""))

I'm trying to add an IF statement to have the formula not deduct anythingfrom the total hours if equal or less than 5hrs and greater than 0hrs.

Thanx Much,
