I'm trying to assign a territory based on BillingState field in Salesforce and getting syntax error message Error: Syntax error. Missing "
IF(ISBLANK(BillingState), "None",
IF(CONTAINS("CA:WA:NV:OR:AK:HI”, BillingState), “Pacific”,
IF(CONTAINS("AZ:CO:MT:NM:UT:WY:ID", BillingState), “Mountain”,
IF(CONTAINS("AL:AR:IL:LA:MN:MS:MO:OK:WI:KS:NE:ND:SD:TX:TN", BillingState), “Central”,
IF(CONTAINS("CT:DC:DE:GA:MN:MD:MA:NH:NJ:NY:NC:OH:PA:RI:SC:VT:VA:WV:FL:IN:MI",
BillingState), “East”,
"Unknown"))))))))
