Объединить столбец onumber на основе значения OGroup с использованием цикла while

Проблема кода в том, что я не могу получить значения ONumber для объединения на основе того же значения OGroup

таблица: ztemp ONumber OGroup RowOnly_ID T146 10 3 T591 10 8 T607 10 12 T612 10 16 T713 1021 T704 15 20 T610 15 14 T611 20 15 T47 20 1 T608 25 13 T49 30 2 T722 35 22 T620 40 18 T588 45 7 T594 5 9 T595 5 10 T606 5 11 T618 5 17 T383 70 5 T314 75 4 T703 80 19 T57890 6 

Testing – added print to display variable values

===== START Pre-Loop Values =====

 = Pre-Loop @CatSONum
5 = Pre-Loop @iCounter
0 = Pre-Loop @iSOGroupCount
90 = Pre-Loop @iMAXGroupCount

===== END Pre-Loop Values =====

 ___ START Loop Values ___
5 = @iCounter
4 = @iSOGroupCount
90 = @iMAXGroupCount
 ___ END Loop Values ___

 ___ START Loop Values ___
10 = @iCounter
5 = @iSOGroupCount
90 = @iMAXGroupCount
 ___ END Loop Values ___


Desired Output would be
OGroup  NumOGroup  ONumber
10      5        T146, T591, T607, T612, T713
15      2          T704, T610
20      2          T611, T47
25      1          T608
