Access Query Modification

Hello I have a very small project, I need to get an MS Access Query to update one field in a MySql database. I downloaded the tables via ODBC and put the query together, but when I link the Access tables with the MySQL table I cannot write to either Access or MySql tables. I’ve attached the database. The query name is Inventory Update – Store and it can be found in the Unassigned Objects section, I need to update the very last field (qty) which is a MySql table field by entering the number found in the field just to the left called (New Quantity) I will also need to place a check in the Store Updated field. I will need the freelancer to let me know what they did to correct the query so I can avoid this problem in the future. My maximum budget is $40 USD Thank you for your interest!
