I am getting following error message while importing testcase from excel to RQM? Can anyone help me!

I am using the following in config file.
//---Requirements
// Start looking for requirements after row 2
requirement.XLSStartRow=2
requirement.XLSArtifactID=A
requirement.dc:title=B
//requirement.dc:description=C

//---Test Scripts
// Start looking for scripts after row 2
testscript.XLSStartRow=2

// use the data in the first row of a found script's column B
// Test script is using the same XLSArtifactID as requirement
testscript.XLSArtifactID=A
testscript.dc:title=F
testscript.dc:description=G

// the literal "execution" will be put into the step type tag, so all steps will be of type execution
testscript.steps.type="execution"
testscript.steps.description=J
testscript.steps.title=F
testscript.steps.name=F
testscript.steps.expectedResult=K

// Pre-Condition
testcase.Section("myns:com.ibm.rqm.planning.editor.section.testcasePreCondition","RQM-KEY-TC-PRE-COND-TITLE")=H

// a new script starts when we encounter an empty row
testscript.XLSDelimeter=\n

//--- Test Case
// Start looking for test case after row 2
testcase.XLSStartRow=2

// a new test case starts when we encounter an empty row
testcase.XLSDelimeter=\n

//Test case and requirement are having the same XLSArtifactID
// This is for the TestCaseUpdater Utility
testcase.XLSArtifactID=A
testcase.XLSArtifactID=E
testcase.ID=requirement.XLSArtifactID


//Link test case to requirement
//This line will link test case to all requirements in the xls file
//testcase.requirement=requirement.identifier

// Categories are defined in a special way
testcase.category term="Category".value=D
testcase.category term="Function".value=D

// Link test case to test script
// self referential links must be declared before also using column definitions
// Below lines will create test case and test script in same name but they can link each other
testcase.dc:title=testscript.dc:title
testcase.dc:description=testscript.dc:description
