    Summing Nulls

    I have revenue data that comes in as text. Sometimes the field contains a 0 sometimes it is null when it is not an actual revenue amount.
    I create a table using a query where I am trying to change the text to number so I can add the values together in another query.
    Code:
    Install_Credit: IIf(IsNull([Rental Credit Install Revenue]),0,[Rental Credit Install Revenue])
    Install_TCV: IIf(IsNull([Rental Install TCV]),0,[Rental Install TCV])
    The make table creates these fields as Number Double - which is great

    When I try and add them together I get a datatype mismatch.
    Code:
    Total Install Rental Revenue: Sum([Install_TCV])+Sum([Install_Credit])
    I am assuming it is the 0 that comes in as text but I can't figure out how to handle it

    Thanks in advance

    Try Sum(CDbl([Install_TCV]))+Sum(CDbl([Install_Credit]))

    If it's Null, wrap each field in the Nz() function:

    Nz(FieldName, 0)

    I tried that too and got the same datatype mismatch error. I am not sure why.

    You're sure the data type is number in the table? Can you attach the db here?

    db.zipI attached it.

    EXEC_SUMM gets imported - everything is text
    STEP_1 is run - everything is still text
    qry_IOPS_Tracker is run - revenue fields are converted to Number
    IOPS_FINAL_TRACKER_CM Is run - datatype mismatch error

    Thanks for looking at this for me

    Try deleting the summed fields and see what happens. The error is coming from the Year([YEAR_MONTH_NUM]), as the field isn't a date/time field. Try the Left() function if you want to leave it as text.

    db2.zip

    ok I added an update statement to deal with the YEAR_MONTH_NUM issue but the numbers are still not summing right. If you look in the IOPS Tracker table under Agency/Direct Column for SUPERIOR DIGITAL you will see there is revenue showing in the SumOfRental Credit Order Revenue and SumOfRental Credit Install Revenue Fields but when you run the IOPS_FINAL_TRACKER_CM query - SUPERIOR DIGITAL comes up blank.

    I have readded the db with my changes

    Adding the Nz() function I mentioned makes it return a value.
