I have a string such as "5/12/2014 1:14:50 PM" and I am trying to extract the date (5/12/2014) from that string. I tried using (Created.Value contains the string):
SUBSTRING(Fields!Created.Value, 1,9)
But it gave me an error saying "The Value expression for the textrun 'Created>Paragraphs[0].TextRuns[0]' contains an error: [BC30451]Name 'substring' is not declared."
