if and with or statement

[Ksisterhen]

I am trying to get this formula to work and am getting an error, why is that

IF [PLN_CD_ID]="MZCT_STR_001" and [mzct earliest day between first sig]<30 or [mzct days between last signed date]<30 THEN "signed prior to assessment date" ELSE [queue] endif

@Ksisterhen Try putting "[mzct earliest day between first sig]<30 or [mzct days between last signed date]<30" all in parentheses so it's seen as a single condition.
