How to define an oldValue parameter?

I want to add an oldValue parameter to DataStore2's ":Update()" method. This is what I currently have now:

view source
1function DataStore:Update(updateFunc)
2    updateFunc(DataStore:Get(0))
3    self.value = updateFunc(self.value)
4    self:_Update()
5end

But it's still nil (printed). Help?

How i print it:

view source
1datastore:Update(function(oldVal)
2    print(oldVal)
3end)

:_Update() function which is used for setting data in DS2 (Used by datastore:Set() and datastore:Update() in DS2):

view source
01function DataStore:_Update(dontCallOnUpdate)
02    if not dontCallOnUpdate then
03        for _,callback in pairs(self.callbacks) do
04            callback(self.value, self)
05        end
06    end
07 
08    self.haveValue = true
09    self.valueUpdated = true
10end

Can you post full script so I can see what were dealing with here? SharkOwen_dev 69 — 4y
