I'm trying to sum volumes in a table, however I have more than one unit of measure (liters and milliliters). I created the following in the 2007 Access Expression Builder, but when I run the query, the /1000 (to take mL to L) does not calculate. - CONVERT: IIf([UOM]="Milliliter*",[VOLUME]/1000,[VOLUME])
Any suggestions on how to fix?!
Of course, it may be simpler and more reflective of the logic if you used : - CONVERT: [Volume] / IIf([UOM] Like 'Millilitre*',1000,1)
As well as reflecting the proper spelling of Millilitre ;-)

Maybe a typo. Why do you have a caret after Milliliter?
cheers,
Its not a caret, its a * wildcard, in case there is anything after milliliter.

If it's a wildcard character then you need to use "Like" rather than "=".
Then like Neo says you cannot use an equal sign. The qual sign will look for a literal match and by your answer you will never find a record in your table where the column UOM="Milliliter*".
Change the equal sign to the word LIKE as indicated by Neo and see if that helps you.
cheers,
- CONVERT: IIF ([UOM]LIKE"Milliliter*",[VOLUME])/1000,[VOLUME])
I'm getting an error stating that the expression contains invalid syntax, or you need to enclose your text data in quotes.
Now what?
Thanks for your help mshmyob and Neo
That is because there is no statement or expression called [UOM]LIKE"Milliliter*".
Try adding proper spacing like so
Also I noticed you are missing an opening bracket: ie: you have one "(" and two ")".
