I want to add to stock via EP, not overwrite

[sbbemn]

Note: upgrading soon, I know

My plan is to upload stock received to admin via EP but ADD to current stock.

Three columns:
1. v_products_id
2. v_products_model
3. v_products_quantity

At my line 1561 a query selects the current contents...
$sql = "SELECT
p.products_quantity as v_products_quantity,

I see in my line 1980 this...
$query = "UPDATE " . TABLE_PRODUCTS . " SET
products_quantity = '" . zen_db_input($v_products_quantity) . "' ,

In order to do this, is it simply '" . zen_db_input($v_products_quantity + p.products_quantity) . "'

If, by EP you mean easy populate, you should ask your question in that mod's support thread.
