Experts,

I get an error of Wrong Number of Arguments.  Do you see where the error is?  
The below use to be an IIF (that worked fine) but I switched it to a "SWITCH" because I needed to add another condition.  I imagine it is a syntax somewhere.  thank you.

MyGroup: Switch(([tblStatus.Status] Like "*Awarded*" Or [tblStatus.Status] Like "Won*" Or IsNull([ContractAward])=False,"Awarded - within last 60 days", [ATTApprvDate] Is Not Null and [ContractAward] is Null, "Went to ATT but not Awarded", GetGroup([Projects.BidCloseDate],[Projects.ATTApprvDate],[Projects.ATCApprvDate],[Projects.ATSApprvDate],[Projects.ContractAward],[Projects.CorpATTDate],[Projects.ExpectedContractAward])))

If GetGroup returns a True/False response then you're missing the argument after it if the response is True.  If GetGroup returns a response other than True/False, this needs to be dealt with first.

Wait a minute, did you want to return the result of GetGroup if neither of the first 2 criteria wetter met?  If so, then add "TRUE," (without the quotes) right before GetGroup.

I added the TRUE and I dont have any errors.  BUT it doesnt want to save it?  


I Have it as follows: (only difference from initial post is the "True" (in bold) and when I tab out it doesnt give any errors and I close and save but when I open again it reverts back to the original.
Strange. Any idea why it it wont save as below?

MyGroup: Switch(([tblStatus.Status] Like "*Awarded*" Or [tblStatus.Status] Like "Won*" Or IsNull([ContractAward])=False,"Awarded - within last 60 days", [ATTApprvDate] Is Not Null and [ContractAward] is Null, "Went to ATT but not Awarded","True", GetGroup([Projects.BidCloseDate],[Projects.ATTApprvDate],[Projects.ATCApprvDate],[Projects.ATSApprvDate],[Projects.ContractAward],[Projects.CorpATTDate],[Projects.ExpectedContractAward])))

1. Too many parenthesis.

2.  When wrapping [table.field] in brackets, each should have its own opening and closing brackets [table].[field]

3.  As IrogSinta indicates, you must have an even number of parameters.  Your call to GetGroup must either return a True/False value or be evaluated against some other value to get a True/False.  Then you need to return a return value for the Switch statement for that element.

4.  I always (while debugging a Switch statement) include a final pair of parameters  (True, "No Match") in my Switch statements so that I can identify records that don't meet any of the parameters provided.  

Switch([tblStatus.Status] Like "*Awarded*" Or [tblStatus.Status] Like "Won*" Or IsNull([ContractAward])=False,"Awarded - within last 60 days",
[ATTApprvDate] Is Not Null and [ContractAward] is Null, "Went to ATT but not Awarded", GetGroup([Projects].[BidCloseDate],[Projects].[ATTApprvDate],[Projects].[ATCApprvDate],[Projects].[ATSApprvDate],[Projects].[ContractAward],[Projects.CorpATTDate],[Projects.ExpectedContractAward]), "Get Group", True, "No Match")

As I mentioned, don't include the quotes. It's just True,

If you need a refresher on how to use the Switch function, please have a look at my article here.

I think Ron has nailed the reason you are getting that error: You have an odd number of arguments in your Switch expression, which is a no-no.  If your intent is, "if all else fails, then return the value from the GetGroup() expression", then Ron is correct that you need to preface that with an expression that is always true:

MyGroup: Switch([tblStatus.Status] Like "*Awarded*" Or [tblStatus.Status] Like "Won*" Or [ContractAward] Is Not Null,"Awarded - within last 60 days", [ATTApprvDate] Is Not Null And [ContractAward] is Null, "Went to ATT but not Awarded", True, GetGroup([Projects.BidCloseDate],[Projects.ATTApprvDate],[Projects.ATCApprvDate],[Projects.ATSApprvDate],[Projects.ContractAward],[Projects.CorpATTDate],[Projects.ExpectedContractAward]))

Open in new window


Note that while the simple boolean value True is sufficient, you can also do things like 1=1.  I address this "none of the above" option in my article.
