I know this must be simple but I haven't found the correct answer.

Code:

al = getAddressList();
myitem = memoryrecord_getAddress(addresslist_getMemoryRecordByDescription(al, "Unequipped Item Dagger Num"))
for x =0, 252 do
myitem.Value = 14
end

The code identifies the correct table location, but I get "attempt to index a number value (global 'myitem')
Script Error"
So what is the correct way to change the value?

ETA: I knoiw there should be a myitem = myitem + 1 in the code.

don't get the address just use the memory record.
Also the variable AddressList was added instead of having to call the function and it's a complete userdata object now so you can call methods on it rather than having to pass it around so you can do just

Code:

myitem = AddressList.getMemoryRecordByDescription('Unequipped Item Dagger Num')
myitem.Value = 14 -- or whatever, the loop makes no sense even with a +1

If you're getting a lot of records and want to save some typing without using a table and loop then you can do

Code:

local getmr = AddressList.getMemoryRecordByDescription
myitem = getmr('Unequipped Item Dagger Num')
...

If "Num" in the the description/name is supposed to be an actual number eg 'Unequipped Item Dagger 0' then the loop makes more sense lol and you'd do something like

Code:

for i=0,252 do
local mr = getmr('Unequipped Item Dagger ' .. i)
mr.Value = mr.Value + 1
end

Code:

for i=0,AddressList.Count do
local mr = AddresList[i]
if mr.Description:find('Unequipped Item Dagger %d') then
mr.Value = mr.Value + 1
end
end

which would work for any number of items without having to hardcode it and risk it breaking if more are added or any removed at some point.

I'm attempting to increment the address locations by one.

This gives the similar type of error like I was getting.

Thanks for replying. The Num is a descriptor, it has no value, the value is at the address. As I said the addresses incriminate by one.

ETA:
Tinkering around most of the day, This works

Code:

al = getAddressList();
myitem = memoryrecord_getAddress(addresslist_getMemoryRecordByDescription(al, "Unequipped Item Dagger Num"))
for x =0, 252 do
writeBytes(myitem, 14)
myitem = myitem + 0x01
end--for x =0, 252 do
end;--function (sender)

Now I don't understand how +1 fails, but 0x01 succeeds.
