Working with records

Hey gang:

I'm creating a customer look-up interface. I'm essentially querying the entity-backed records to determine if a customer exists in the database. It has two parts, the first component is the record picker. The second component is just a read-only field that displays selected fields from the record. This is what I have:

load(
  local!storedRecord,
  a!formLayout(
  label: "Customer Look-up",
  firstColumnContents: {
    a!pickerFieldRecords(
      label: "Customer Name",
      labelPosition: "ABOVE",
      instructions: "Type the name of the customer",
      maxselections: 1,
      recordtype: cons!FSRC_CUST_REC_PICKER,
      value: local!storedRecord,
      saveInto: local!storedRecord,
      validations: {}
    ),
    a!textField(
      label: "Selected Customer",
      labelPosition: "ABOVE",
      value: if(
        isnull(local!storedRecord),
        "",
        rule!FSRC_queryCustomerRecord()
      ),
      saveInto: local!storedRecord,
      refreshAfter: "UNFOCUS",
      validations: {}
    )
  }

rule!FSRC_queryCustomerRecord:

 =queryrecord(
      cons!FSRC_CUST_REC_PICKER,
      a!query(
        filter: a!queryFilter(
          field: "customerID",
          operator: "includes",
          value: local!storedRecord
        ),
        selection:a!querySelection(
          columns:{
            a!queryColumn(
              field:"firstName"
            ),
            a!queryColumn(
              field:"lastName"
            ),
            a!queryColumn(
              field:"custAddress"
            ),
            a!queryColumn(
              field:"customerID"
            )
          }
        ),
        pagingInfo: a!pagingInfo(
          startIndex:1,
          batchSize:-1
        )
      )
    )

This, however, produces the error:
