I want to work using If formula as alternative, however formula work upto w column only, while using X column errors appeared as " Your formula missing parenthesis--) "

Formula is....
(IF(H2=I2,I5,(IF(H2=J2,J5,(IF(H2=K2,K5,(IF(H2=L2,L5,(IF(H2=M2,M5,(IF(H2=N2,N5,(IF(H2=O2,O5,(IF(H2=P2,P5,(IF(H2=Q2,Q5,(IF(H2=R2,R5,(IF(H2=S2,S5,(IF(H2=T2,T5,(IF(H2=Q2,Q5,(IF(H2=U2,U5,(IF(H2=V2,V5,(IF(H2=W2,W5,(IF(H2=X2,X5,0))))))))))))))))


Please help me out to resolved the issue

This ..

=IF(H2=I2,I5,IF(H2=J2,J5,IF(H2=K2,K5,IF(H2=L2,L5,IF(H2=M2,M5,IF(H2=N2,N5,IF(H2=O2,O5,IF(H2=P2,P5,IF(H2=Q2,Q5,IF(H2=R2,R5,IF(H2=S2,S5,IF(H2=T2,T5,IF(H2=Q2,Q5,IF(H2=U2,U5,IF(H2=V2,V5,IF(H2=W2,W5,IF(H2=X2,X5,0)))))))))))))))))

OR

=INDEX($I$5:$X$5,MATCH($H$2,$I$2:$X$2,0)) ?????
