Questions
1

For x = 1,maxn,30 do – reads a table every 30 fields

Na=a[x]…“;”

String = string…na

End

Any help on this problem would be so helpful as I can no further until this has been solved. I am trying to create a string with every 30th field

Cheers

If you want to add the string to itself:

String = String..Na

Variables are case sensitive. It should also be for not For and end not End.

@Jazmal I think this is what your asking. If not, let me know.


function setup()
    tab={}
    
    for z=1,1000 do    -- create a table with 1000 entries
        table.insert(tab,"entry "..z)
    end        
    
    str=""    -- initialize str
    
    for x=1,#tab,30 do    -- read every 30th entry
        str=str..tab[x]    -- append each 30th  entry to the previous one
    end
    
    print(str)    -- print selected entries
end

for x = 1,#a do 
        if x%30 == 0 then
            print("30th Field!")
            Na=a[x]..";"

            String = String..Na
        end
    end
