Custom Label in Javascript Button

Question

Can anyone help me with the syntax for using a custom label in a Javascript button. Essentially, I am trying to direct users to different pages based upon whether the Opportunity Record Type contains the 15 character ID string contained in a custom label. My code is below:

    if('{CONTAINS(Opportunity.RecordTypeId,$Label.ENT_CommitRT_ID)}' == 'TRUE'){
window.open('/apex/opportunityProductEntry_Exclusive?id={!Opportunity.Id}')
}

else{
    window.open('/p/opp/SelectSearch?addTo={!Opportunity.Id}&retURL=%2F{!Opportunity.Id}')
}

The problem is that no matter what record type the Opp has, it always defaults to else condition.

You have two notable problems with your logical evaluation:

• You're missing the bang character (!) required in merge syntax.
• You don't need to compare strings. Just use the Boolean output directly (if({!...})).

Instead of:

if ('{...}' = 'TRUE')
//    ^ missing !

Use:

if ({!...})
//  ^^ don't wrap in quotes
