I have a query that runs a main audit form, all of the fields except for the calculated ones are in the main table, amongst these are a set of error code fields, these error code fields are used during the audit process by combo boxes in the audit form and their data is provided using a select statement in the combo box properties. all of this works fine, however in the table that the select query(s) refer to for its values is a corresponding field that has a number in it. to use these corresponding fields to produce a score I add in a column in the query for each error code field and then a column to calculated the score after the user selects the various error codes allowed, to get the valuse I bolt on the ref table that contains the number field(s), so we start with a score of 15 and each time an error is selected the score can drop by the number in the corresponding number field. so my issue/problem is this, when I strapthese tables onto the main table in the query I cannot edit any fields in the main form, if I remove them I can edit the fields I need to but get no calculated scores etc, I have checked all of the properties etc and all are set to allow updates.. Im stumped, JB
