VLOOKUP with checkbox

Hi,

 

I have a check box in one of my object and its functioanlity is, if a record is created with that check box "checked", no other records can be created with that checkbox "checked" , need to show an error that " other record has been checked "

 

So I have written a validation rule as below :

 

AND(VLOOKUP($ObjectType.xenonproto__Level2__c.Fields.xenonproto__Goal_Level2__c , $ObjectType.xenonproto__Level2__c.Fields.Name , Name)==True,
VLOOKUP($ObjectType.xenonproto__Level2__c.Fields.Id , $ObjectType.xenonproto__Level2__c.Fields.Name , Name) != Id)

 

 

Note: here Goal_Level2__c is of type checkbox.

 

but the above validation is not working for me.

 

Please anyone suggest me.

 

Thanks and Regards,

Haripriya.

I don't think VLOOKUP() is going to be able to do what you need it to do here. All VLOOKUP() does is fetch a single record -- based on a pased in value -- of a certain object type, and return a value from some other field on that record. It doesn't check multiple records. For example, you could have a Zip Code object where the name is a 5-digit zip code, and return the State field -- but you would be passing in a single zip code and returning a value from a single record.

 

It sounds like what you want to do is loop through all records to see if they have a certain field checked, and return true if any one of them does. You're going to need to use a trigger for that.

I think In red text there is no need of == single = is enough since it is not a if condition in OOPS program.
