Telerik Reporting IIF Function Error

[Ebenezer]

I am trying to print three statements using the following expression, but getting Error: "An error has occurred while processing TextBox 'textBox5':
An error has occurred while executing function Len(). Check InnerException for further information". when the third statement is added.

=IIf(Len(Fields.Ledger2)>0,Trim(Fields.Ledger2) +'.','')    =Fields.Title1
                                                                                          =Fields.Statement1 
                                                                                          =Fields.Type1 <------------------- Error when this statement is added


 This statement  below works fine. What am I missing? Any help will be appreciated see screenshot

=IIf(Len(Fields.Ledger2)>0,Trim(Fields.Ledger2) +'.','')    =Fields.Title1   
                                                                                          =Fields.Statement1
