How to get the values of the same elements of the table and make their sums

[Lena19]

Hello all,
I have an array of measurements where some elements of the array are repeated but with different values.

How to get the values of the same elements of the table and make their sums?
I need help to do this please

It is just some string and array manipulation. If you are not familiar with those functions, try not to use Quick Drop but right-click on the block diagram and explore the palettes.
