Could you please explain what's wrong with this syntax?

Hello everyone,
Where is the problem with this syntax? Please accept my sincere thanks
IF( ISPROJECTMAINORDER = '-1'
AND
ordercategory_code = '100'
AND
(sum(Total_cost_price_pbd) > 0.0), Total_cost_price_pbd,

(ISPROJECTMAINORDER = '-1'
AND
ordercategory_code = '100', TOTALNETAMOUNT * 0.65,
sum(SO_costprice)))

I think you were missing an If statement. I've added that and reformatted so that you can check the logic.

See the second If statement in the code blow.

IF( ISPROJECTMAINORDER = '-1'
            AND
        ordercategory_code = '100'
            AND
        (sum(Total_cost_price_pbd) > 0.0), 
    Total_cost_price_pbd,
    If(   ISPROJECTMAINORDER = '-1'
                    AND
                ordercategory_code = '100', 
            TOTALNETAMOUNT * 0.65,
            sum(SO_costprice)
      )
  )
