query won't update table????

[mkelly]

I have a form that runs off a query, there is a text box 'cosr per copy 1' that auto populates a cost once a copy type is selected from a combo box. in my query I also have 'cpc 1' field that links to the job table and it is set "CPC 1:cost per copy 1" when the form is open it will capture the data. However it will not save the information to the table. does anyone know how I can get this to save??

all suggestions appriciated...
