(Online Store) Need a small SmartyEngine Code for stock import with .csv file

Hello,

I have an Import Tool for my Online Store. With the tool I can import products, images or article stock.

In this import tool, I have an advanced function which is working with smarty engine. With this function I can add smarty variables and change import columns. Here are 2 screenshots.

I need a solution for this problem:

In my .csv file I have an column with stock for every product in my store. When I import the .csv file, the new stock have to sum with old stock wich is allready in my store.

One example:

1. Article Blue Shoes have 5 pieces on stock

2. I import the .csv file wich have 10 new pieces

3. After the import, the stock must be 15

This is everything. With actual preference the import tool only replace the stock and I see in my store 10 after import, which is wrong .

Need help urgent!!!!!

Thank You :-)))
