Creating a Measure from a Dimension

[Goodman_UPS]

I have a dimension that I created called Proposed Bucket.

Here is my if statement:

=If(Excp_Category='6-Attempted','2-CUSTOMER ACTION',

if(Excp_Category = '1-Manifest','5-APPLE ACTION',

    If(Excp_Category='5-Out for Delivery','3-OUT FOR DELIVERY',

    if(Current_Scan_Activity_Record_Type='Out For Delivery','3-OUT FOR DELIVERY',

    IF(Excp_Category='7-Delivery','1-DELIVERED', [Exception_Resolution_Proposed_Bucket])))))

I want to create a measure that adds up certain elements of this proposed bucket.

Sum({$<[Proposed Bucket]={'2-CUSTOMER ACTION','1-DELIVERED'}>} Measure)

[Goodman_UPS]

I get error in expression when used.

It was simply an example that needed to be adjusted to reflect field names in the model.

Perhaps you could post a sample of the dataset.
