The report is throwing an error "Data type mismatch in criteria expression" This leads me to believe that the data being imported into the DB is not compatible with the data types set in the report's query. Is there a good way to trouble shoot the statement in Access to find which piece is causing the error? I'm just getting back into using Access so I'm a little rusty. Look at those specifically. The error message means you're comparing two things this equals that, or this less than that, etc.
You can find out which condition is causing the problem by deleting them one at a time and testing again each time until the error disappears.

For example, if you give Access a text string when it is expecting a number, you receive a data type mismatch error.
If you just changed the Default Value for a field in a table and see a message about data type mismatch when you try to enter new records, open the table in Design view and make sure the expression you use for the field's Default Value evaluates as the same data type as the field. For example, if the field has the Number data type, make sure you don't put quote marks around the Default Value expression e. Verify that the criteria for a column matches the data type of the column's underlying field.
So be sure to remove those quote marks. You're specifying criteria for a Lookup field, and the criteria use the values that are shown like a name in the lookup list instead of their associated foreign key values like an ID. Because the foreign key values are the values actually stored in the underlying table, you should use them when you specify criteria for a field.
Remove the dollar sign, and then view the results. You can tell if the numeric criteria you entered isn't a number if it has quote marks around it. Well, it may be in the relationships, I didn't look there. You'd access what I saw by looking at the form's record source property. In that, there was join between those incompatible fields.
I'm on an iPad right now and can't look at the db. Megacitizen said:. Thanks for your reply, but now I'm really lost Not sure where to access the source query so that the join can be viewed, and when I can, how to rectify the situation. I initially thought you were referring to relationships. As far as I'm aware, I have the correct setup for the relationships I require. See attached, which is the source query of your form its Record Source.
Thanks Paul I though I had already got rid of that join, but my system had kept a record of it somewhere, somehow, and THAT was what was stopping me from proceeding. I just got rid of the entire file and started again, which thanks to numerous previous attempts, only took a couple of minutes to redo. Happy to help! You must log in or register to reply here.

A valid value will be only — — without the quotes. Thus, it will be interpreted as a String instead of currency and an error will be thrown. You need to remove the dollar sign, and then view the results. Because the foreign key values are the values actually stored in the underlying table, you should use them when you specify criteria for a field. Your email address will not be published.
