what is the wrong

local data01 = {
    19, 29, 39, 49, 59,
}
for i = 1,data01[1],1 do
    if item.vnum == data01[1+1*(i-1)] then
        mount_levelup.upgrade_mount(50067,2)
    else
        say(gameforge.training_mount._63_say)
    end
end

You're getting out of the index with this code!

Your for loop doesn't look correct and therefore results in this behaviour. What you're doing is:

for i = 1, data01[1], 1 do

Which means exactly this:

for i = 1, 19, 1 do

So the loop will go from 1 to 19, but the table only has 5 entries. Now we can look at the code:

if item.vnum == data01[1+1*(i-1)] then

In which case is the loop out of index? It's when 1+1*(i-1) > 5

So in your case it'd be at the 6th execution. That's the point where i=6 and the solution would be: 1+1*(6-1) > 5 and yes, 1+5 > 5

 

What you may wanted to do was this:

for i = 1, table.getn(data01), 1 do

This will only iterate through the table until it reaches the maximum. Also the Computation doesn't make sense. Why aren't you just using

if item.vnum == data01[ i ] then

instead of your code?
