Append query (1 Viewer)

[rutica]

I am trying to write an Append query that has a math formula. Part of the formula is to look at a text field called LastFullMonth (contains values such as January, February, etc) and do a calculation based on how many months have elapsed since the fiscal year. (the fiscal year begins in October).

To come up with the number of months elapsed since October, I tried creating:

sinceOct: IIf([lastfullmonth]="October",1,IIf([lastfullmonth]="November",2,IIf([lastfullmonth]="December",3,IIf([lastfullmonth]="January",4,IIf([lastfullmonth]="February",5,IIf([lastfullmonth]="March",6,IIf([lastfullmonth]="April",7,IIf([lastfullmonth]="May",8,IIf([lastfullmonth]="June",9,IIf([lastfullmonth]="July",10,IIf([lastfullmonth]="August",11,IIf([lastfullmonth]="September",12))))))))))))

Then, my formula is:
Code: IIf(YTDPlannedCost > 1.25 * (TotalSunkCost* (DevOrEnhance+Legislative)) * ([sinceOct] / 12),"Red",Null)

But when I try to run the Append query, it asks for the parameter value of sinceOct.

I can run a Select query, but not an Append query. I tried replacing [sinceOct] in my formula with the 12 IIf statements above, but then Access said my formula was too complex.

Any ideas?
Thanks!

Rather than all those nested IIF statements you might want to look at using the Switch statement

Switch([lastfullmonth]="October",1,[lastfullmonth]="November",2, etc...)

I didn't know about the Switch Function. Thanks!

I typed:
Switch([Project Status Survey Budget]![lastfullmonth]="October",1,[Project Status Survey Budget]![lastfullmonth]="November",2,[Project Status Survey Budget]![lastfullmonth]="December",3,[Project Status Survey Budget]![lastfullmonth]="January",4,[Project Status Survey Budget]![lastfullmonth]="February",5,[Project Status Survey Budget]![lastfullmonth]="March",6,[Project Status Survey Budget]![lastfullmonth]="April",7,[Project Status Survey Budget]![lastfullmonth]="May",8,[Project Status Survey Budget]![lastfullmonth]="June",9,[Project Status Survey Budget]![lastfullmonth]="July",10,[Project Status Survey Budget]![lastfullmonth]="August",11,[Project Status Survey Budget]![lastfullmonth]="September",12)

straight into my formula and it worked! It wasn't too complex for Access.

I wonder if there is a more elegant way to do this by somehow using the Month () function... Just wondering.

But ,it's working now thanks to you.

I received advice today from someone who gave me the following formula that can be used instead of the nested IIF statements or the Switch statement:

Fiscmonth: IIf(DatePart("m",DateValue([LastFullMonth] & " 1, 1900"))<10,DatePart("m",DateValue([LastFullMonth] & " 1, 1900"))+3,DatePart("m",DateValue([LastFullMonth] & " 1, 1900"))-9)

Interesting. Just wanted to share.

Thanks again for your help.
