Using Link() Modifier

I am also trying to use the Link() modifier or LinkExisting(Modifier) as follows. I export content from my Test Case that are in Word to an XML file which I then import into RQM as a RQM Test Case. So, now I have the RQM Test Case ID Number. Next, I place the RQM Test Case ID Number into the Test Procedure Steps table. For example, I place the RQM Test Case ID "10" into Table 1 Column A Row 1 and the Test Steps start in Column B Row 2. I tried to use the syntax shown below to export the ID number as part of the Test Steps so that when I import the Test Steps into RQM as a Test Script a link to RQM Test Case "10" will be automatically established. This syntax does not work. The XML file contains all of the Test Steps from the Word document, but not the RQM Test Case ID Number.
testscript.testcase=Link(Table(1).A1)

I also tried testscript.testcase=Link("10") and that doesn't work either. The XML file contains no reference to the Link ID "10".

Thanks for your help
