Why does this not work:
Evalauate ( "GetRepetiton (" & $$_field_name_rep & ")" )
$$_field_name_rep = AAA:Name 
I cannot get this to render anything, even though value exist in that field repetition.
Because you're mixing two different ways to grab a field repetition.
GetRepetition ( fieldName ; repetitionNumber ) is the same as fieldName[RepetitionNumber]
Try just Evaluate ( $$_field_name_rep )
That fails silently.
Calling the function: EvaluationError ( Evaluate ( $$_field_name_rep ) )
Makes no sense.
OK, math error.
You are right.
Thank you David!
You could try these versions of evalutate to get your result as well.
$$_field_name_rep= GetFieldName ( AAA:Name );
$$rep = 5];
Evaluate( $$_field_name_rep & "[" & $$rep & "]"))
$$tst = GetFieldName ( AAA:Name );
Evaluate( "GetRepetition (" & $$_field_name_rep & " ; " & $$rep & ")"))
In both cases, I'm getting repetion 5. I tried these in the data viewer and set up a field for the test with less repetions then you are using. Both methods worked.
Hope this is helpful.
