Handy function to sum a subset of repeating field reps

This is my Custom Function and I want to edit it


This is exactly what I was looking for. However, the function seemed to be broken until I changed 'rfield' to 'GetFieldName ( rfield )' ... as follows:

Let ( [
nn = If ( to ≠ ""; to - from + 1 ; 200) ;
xx = Evaluate( "MiddleValues (List (" & GetFieldName ( rfield ) & ");" & from & ";" & nn &")" );
lln = Length (xx) - 1 ;
uu = Left (xx ; lln)
] ;
Evaluate( Substitute(uu ;¶;"+")) )

rfield should be inserted in quotes actually: I have added a note to clarify that.

Does not work if some of the repetitions are empty

That's true Martin. I will fix when I figure that out.
One could use as an argument that is the Max of the intended rep field and another that contains only 0's
