From: alhotch on 25 May 2010 17:37 I saw a post that showed how to convert from a number value to a string value. But how about the other way ? Convert a string value to a number value. Example, fieldA contains the text value "YES". fieldB is to contain the numberic value of "1". How would one create a query that would accomplish this task ? "YES" would put the number one (1) in fieldB and "NO" would put the value of two (2) in fieldB.
From: alhotch on 25 May 2010 18:10 Check that. I figured it out. IIF[fieldA]="YES","1", IIF[fieldB]="NO","2",Null This places the number one (1) in the "appended" field YesNo or the number two (2) in the same field, depending on the values of fieldA or fieldB.

From: Jeff Boyce on 25 May 2010 18:59 As written, your IFF() statement checks two different fields for values, not one. And by the way, if you already have a "YES", why do you (also) need a "1"? You wouldn't need to store that "calculated value", you could just use a (corrected) IIF() expression to calculate a "1" or a "2" on the fly...

Do you want a number or a text string that consists of numbers? IIF(FieldA="Yes",1,IIF(FieldA="No",2,Null)) As noted elsewhere, your expression does something different than the text description you posted.
