Hi Kulkul

I have chanced my script and now I retrieve how many item for all Rebar Number inserted.
How can I add these values ​​to get the total for every Rebar Number (for example Rebar Numer 1 =8+10)?

after several tests I came to this result:
I got a list with the total of the bars for each position and a list with the rebar number.
How I can conbine it for obtain a list like this:?
