I am having a problem with a calculation in Microsoft Access. I am trying to add two numeric columns, however the result I am receiving is the data is being concatenated. I am using the following formula: newField:([field1]+[field2]). If field1 contains 567 and field2 contains -98, my result is 567-98 instead of 469. I have performed simular calcualtions many times and I am going nuts trying to figure out why this won't work. I appreciate any help you can provide.

I reproduced your scenario, and this will only happen if you have Field1 and Field2 defined as Text. If they're defined as Numbers you'll get your desired results.
Alternatively, you could use
NewField: Val([Field1]) + Val([Field2])

Thank you, thank you, thank you! I don't even want to tell you how much time I spent on that!
Just out of curiosity, the fields are listed as "numbers" in the original table. However I have them in initial query before appearing in the final query where I am performing the calculations. Does the format not carry over from the table? Also, in the query I tried changing the format to "general number" or "standard number" and had the same concatenating result.
I really appreciate your help.
Don't really know where they got changed to Text, although the output of most formatting does is string/text rather than the original datatype.

This is where the problem is introduced.
The Format() function returns a string value, not a numeric value simply displayed as formatted. It is not generally considered a good idea to convert the value to a formatted string until it is necessary (If reporting, format it in the report rather than any of the intervening steps).
Does that make sense?
Welcome to Bytes!
Yes that makes sense. I have made those changes. Thanks again.

I am trying to design a query that works with a relationship between a
Table and a Query. I am comparing a value in the table with a computed
value inside the query.
The reason for this is that the Query calculates a field to become
identical to the corresponding table field, for instance:
Table 1 contains field "ID", which is WV008A00
Table 2 contains field "ID In", which is WV001000

I am building a query in Access 2003. Here is my problem.
I create an expression called SUN_ST
In a later expression I reference a calculation based on SUN_ST
ie, MON_ST=sum-SUN_ST
SUN_ST is not a value in a table it is a calculation/expression within the query.
How do I reference a query expression within an expression.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
