I have these two working scripted fields:

`def M3 = doc['obj'].value.splitOnToken('_'); return M3.length >= 4 ? M3[3] : null;`

`def M2 = doc['obj'].value.splitOnToken('_'); return M2.length >= 4 ? M2[2] : null;`

that I would like to merge in an unique scripted field using a nested IF statement following these rules:

`if(doc['label'].value == 'MLD42')`

return (M3):  
`doc['obj'].value.splitOnToken('_'); return LU2.length >= 4 ? LU2[2] : null;`

else return(M2):  
`doc['obj'].value.splitOnToken('_'); return LU3.length >= 4 ? LU3[3] : null;`

I still can't do it correctly, please help me with the correct syntax  
Thank you
