Concatenation Issue

I am trying to add a value to my concatenation string and the value is not being inserted in the right place. I am adding onto this code from another developer and cannot seem to get it to work. The only code I have added is underlined in bold red.

This is how the translated HL7 message looks:

OBX|1|CE|CDX^History||Specimen 1 Clinical History: CLINICAL HISTORY\.br\\.br\Specimen 2 Clinical History: CLINICAL HISTORY 2\.br\Specimen 1 Suspected Clinical Diagnosis\.br\Specimen 3 Clinical History: HISTORY 3\.br\Specimen 2 Suspected Clinical Diagnosis

This is how it should look:

OBX|1|CE|CDX^History||Specimen 1 Clinical History: CLINICAL HISTORY\.br\Specimen 1 Suspected Clinical Diagnosis\.br\Specimen 2 Clinical History: CLINICAL HISTORY 2\.br\Specimen 2 Suspected Clinical Diagnosis\.br\Specimen 3 Clinical History: HISTORY 3\.br\Specimen 3 Suspected Clinical Diagnosis
