I have it working on one database A , but the second one B kicks up the "Invalid" error. The report query is generated from another query, which basically grabs the order information and customer information. From there, the query in question breaks up the orders into chunks depending on how long ago they were shipped, and returns the balance.

The error message pops up with the following code segment:. If the Is Null is changed to anything else, the query executes normally. If I try and introduce any "if the variable is null" code, it throws up the error.

I tried the following, but to no avail. I have another column that throws back "NULL" if the shipdate is null, which suprisingly works. The first code segment works flawlessly in the other database, so I'm confused. I need to be able to generate a column for the unshipped orders, hence the missing [ShipDate]. I'm at a loss as to why the code does not work. It's also implemented in about a million places in the database- The designer thought to auto-generate the total balance due every time the query is ran, instead of storing it somewhere.

For example, you can use this function to convert a Null value to another value and prevent it from propagating through an expression. Syntax Nz variant[, valueifnull] The Nz function has the following arguments. Argument Description variant A variable of data type Variant. A Variant that supplies a value to be returned if the variant argument is Null. This argument enables you to return a value other than zero or a zero-length string. Note If you use the Nz function in an expression in a query without using the valueifnull argument, the results will be a zero-length string in the fields that contain null values.

In the next example, the optional argument supplied to the Nz function provides the string to be returned if varFreight is Null. Rich Guest. Oli your problem is that you're re-creating a spreadsheet in Access. You don't need separate fields for each month. Just a couple will do, in simple terms one for the amount and one to define which month the figure relates to.

It may be the same error, but your setup, the code involved May ask end up with a different solution. Which would indicate that you have at least one entry where there is no value for a DepartDate.

If that's the case then you'll need to use IsNull to test before continuing our Nz to assign a default value of the is a null entry. As for the blank record at the bottom of the continuous form, there is no issue. It does not get looped through an.
