Dear Graham:

While you cannot reference a column name from the query inside the Eval() string, you can work around it for simple cases, which is all I expect you need.

For example, in a query, put:

  Eval(CStr([Ingredient Rate]) & "* 7")

and you will get the ingredient rate times 7 as a numeric result.

The string "* 7" could come from another column in another table, where you look up the conversion using the units of measure.

Before going too far, make up a list of all the necessary conversions. If you'll post them here, I'll bet we can solve this in a flash.
