#18 String concatenation implicit type conversion fails

[Warrick Flower]

Using an expression such as (=Globals!PageNumber & " of
" & Globals!TotalPages) fails with the error "The left
operand of string concatenation must be a String". It
should work in this case as the right side is a String.

The expression (="" & Globals!PageNumber & " of " &
Globals!TotalPages) works ok.

System.Exception: The left operand of a string
concatenation must be a String.
