Issues with xPorter Linktype iterations

[s.balerin]

Hi, I would like to fill a cell of an Excel table with a field value only when the issue has a link of a specific type, otherwise put "NA" in the cell. I am facing several issues:

1. I do not find a #else statement for adding "NA".

2. I also want to put NA, when there is no links at all for the issue. Is there a way to check the value of n, so I cant add "NA" when n equals 0? 

Here is the current content of my cell: 

'#{if (%{‘${Links[n].LinkType}’.equals(‘Parent of’)})}
${Links[n].Req. ID}
#{end}
