It doesn't work because Link is a reserved word in UFT. Change it to MyLink and it should work just fine.
Things like Link, Image, Browser, WebButton, etc. are Test Object Classes. Per [UFT documentaion][1], ''Reserved words in UFT include the names of all UFT test object classes, methods, and properties, as well as F-keys (F1, F2, and so on).''
You can check the [UFT Object Model Referenc For GUI Testing][2] to find all the object classes, mehtods and properties for the various technologies.
