Linking Multiple Test Cases with a single script during Upload

I am using the Excel Importer to upload a series of Test Cases and associated Test Scripts.  I have the situation where a number of test cases are linked to the same script.  My configuration file will link the test script to the 1st Test Case but the remaining test cases are not created at upload, and so do not link to the test script.  Can anybody advise on what is wrong with my cfg file below (I am still using RQM 3)

testscript.XLSStartRow=3

testcase.XLSStartRow=3

testscript.dc:title=A

testscript.XLSArtifactID=A

testscript.dc:description=B

testscript.steps.type="execution"

testscript.steps.description=C

testscript.steps.expectedResult=D

testscript.alm:state="com.ibm.rqm.planning.common.approved" 

testcase.XLSDelimeter=\n

testcase.XLSArtifactID=F

testcase.dc:title=F

testcase.dc:description=G

testcase.Section("myns:com.ibm.rqm.planning.editor.section.testCaseExpectedResults","RQM-KEY-TC-EXP-RESULTS-TITLE")=H

testcase.alm:state="com.ibm.rqm.planning.common.approved" 

testcase.category term="Function".value=I 

testcase.category term="Team".value=J

testcase.category term="Type".value=K 

testcase.weight=L

testcase.XLSLink=testscript

testcase.testscript=Link(A)

Many Thanks,

Chris
