[JASS] I really need some explanation

[Starquizer]

Why does this

function create takes nothing returns nothing
    local unit temp_u
    local integer i = 0
    local integer j = 0
    loop
        exitwhen i >= 5
        loop
            exitwhen j >= 5
            call BJDebugMsg( "(" + I2S(i) + "," + I2S(j) + ")" )
            set j = j + 1
        endloop
        set i = i + 1
    endloop
endfunction

print:
(0,0)
(0,1)
(0,2)
(0,3)
(0,4)

Also hashtables is returning null in the map containing the above code.

If you are concerned

This is the link to the thread that contains the totally bugged map

<<< EDIT >>>

1st problem solved but the second in the Hidden tags is not solved.

Because you didn't set j=0 after exiting the second loop.

Yes, I realized that that's why I quickly added the EDIT sign to prevent people from wasting time reading it. Anyway, thanks.
