I am trying to create a text formula field called "Check number of mobiles captured":

        ISBLANK( Account.No_of_Mobs__c ), 

This is a text formula field which checks Account.No_of_Mobs__c (number field) to find out if it is blank.

However i am getting the following error

Error: Incorrect parameter type for function 'TEXT()'. Expected Number, Date, DateTime, Picklist, received Text

can someone please help on this? much appreciated

The result of your IF() is either "yes" or "no"

both of those are already of type Text, as evidenced by the error you're getting saying that you're trying to pass something of type Text to the TEXT() function.

Just get rid of the TEXT() and keep the stuff inside of it (i.e. keep the entirety of the IF())

  • thank you Derek this worked :)
