IF Function with Multiple Criteria

[excel_learner]

not working bracket error, my original formula is as below, it does not move,

=IF(ISNA(MATCH(I3,PC_CC,0)),IF(ISNA(MATCH(R3,Risk_ country,0)),IF(AND(K3>=$KP$1,K3<=$KQ$1),(U3*206537 50)/$D$4772,0),IF(I3=14,IF(AND(K3>=$KP$1,K3<=$KQ$1),(U 3*150030)/$D$4779,0),0))),0) where pc_cc includes 14,51,33 etc and risk_country includes CN, RU, etc.

and if i change to

=IF(ISNA(MATCH(I3,PC_CC,0)),IF(ISNA(MATCH(R3,Risk_ country,0)),IF(AND(K3>=$KP$1,K3<=$KQ$1),(U3*206537 50)/$D$4772,0),IF(I3=14,IF(AND(K3>=$KP$1,K3<=$KQ$1),(U 3*150030)/$D$4779,0),0)),0)

it does not perform the IF(I3=14,IF(AND(K3>=$KP$1,K3<=$KQ$1),(U3*150030)/$D$4779,0),0)),0) returns 0.
