Flash - Cannot Get Data Out Of Dataprovider In Flex Application

I am building an app for a website that will filter through the shops carrying some products/brands and show the results in a List component. I got all the way up to loading the data, putting brands/countries/cities in comboboxes so a user can filter in which country and city he wants to look and for which brand. No problem till now. My problem is that while the dataprovider works as it should when hardcoding some values to the labels that I use for the item renderer of each entry, I cannot get the real data from the data provider. You will see in the code below, that in the VGroup component (which I use for each shop in the list) there are 4 labels, where 3 of them are hard coded, just to see it works.

One of the labels though is trying to get the real data from the xml file and thats where I stop. In all the tutorials i ve seen (and documentation too) everybody just hits "data.XYZ" where XYZ is the name of the attribute or node to get. Doing the same in my case just returns an error of "1120: Access of undefined property data.". There is also an xml file but its loaded correctly and the different xmlLists DO have the correct nodes stored, so I do not think it needs to be posted, unless you think otherwise. The xml nodes for each shop are "title", "tel","mail","city" and I am stuck trying to get the title. The function that matters the most is the filterShops one and then of course the whole list and itemrenderer block.
