Hello guys,
I’m doing a stock list that fill itself with the data of the tables in a server (like an inventory system for a mmorpg). for that, I’m using a Web.cs that call the info from a php file and a Stock.cs that is using the info obtained to create an item Stock for each StockID and fill the name with the Name of the item.
the error that I’m obtaining is:
Error CS7036 There is no argument given that corresponds to the required formal parameter ‘callback’ of ‘Web.GetStockID(string, Action)’
at my Web.cs
i think that is because Stock.cs. I’ve been checking and i cant spot why, please help me.
thanks.
PD: im leaving the scrips below (first web, and then stock):
