LINQ: The specified type member is not supported in LINQ

I am trying to run the linq statement below. I am getting the following error message:

The specified type member 'CustomerID' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.

I stepped through the code and it happens when I take query and attempt to convert using "ToList()".

Any ideas? How would I rewrite this query so that LINQ to Entities stops complaining.

                var query = from l in db.QBPOLines
                            join t in db.tblJobTasks on l.POID equals t.PurchaseOrderID
                            join j in db.tblJobTasks on t.JobID equals j.JobID
                            join c in

                                {
                                    c.CustomerID,
                                    PricingID = c.PricingID == null || c.PricingID == 0 ? 1 : c.PricingID
                                }
                            ) on j.CustomerID equals c.CustomerID

                                    : (m.CustomerPriceField == "PS_FZ50" ? p.PS_FZ50 :
                                       m.CustomerPriceField == "PS_FZ75" ? p.PS_FZ75 :

                    Rate = i.Rate
                });

I believe the problem is that you can't join on a collection of anonymous types.

Move the PricingId property to a later let clause and join directly to Customers.
