Updating a table

[bigbadbess24]

I want to create a form that will update a table. I have two columns, an item number and a paid column. On the form I want to plug in the item number and then I want to hit ok and it will find that item number and put a value (for example "X") in the paid column.
I have tried running an update query when i hit the ok button but I can never get to work

post your update query

This is what I have now. I need something to link it to the item. My other column is Item Number.
UPDATE tblDescription SET tblDescription.[Printed Recipt] = "X"
WHERE (((tblDescription.[Printed Recipt])=[Forms]![frmPaddleWinner]![Paid]));
