AutoCAD Inventor :: Editing Prompted Entry Values With ILogic

I have been attempting to automate some prompted entry (PE) values using iLogic and the SetPromptResultText command.

The command works on the customer-supplied template I have if I create a new PE called <DELETEME> - my code also works on this new PE even if I delete the "<" & ">" from either end of the string so it becomes "DELETEME".

The command doesn't work on the customer supplied fields of "PURPOSE OF ISSUE" & "PROJECT REF No" but if I add < & > to either end (so they become "<PROJECT REF No>" & "<PURPOSE OF ISSUE>" respectively) and modify my code to look for that instead, lo and behold it works.

why it works with the "<" & ">" on the ends of the string but not without?

My guess is that the "<" & ">" allow the PE to have spaces and without it Inventor 2013 throws the dummy in the dirt and refuses to play nice! - Just tested that theory and it's clearly cobblers.

Here's the sub-routine I wrote (with the working "<" & ">" still in place):
 
Sub UpdatePromptedEntries(oDoc As DrawingDocument)'assumes the oDoc is activatedDim oPromptEntryDim actSheet As Sheet = ThisApplication.ActiveDocument.ActiveSheet'For Each oSheet In ThisApplication.ActiveDocument.SheetsFor Each oSheet In
