Print Datagridview Cell Format

Question

Hi All
I am using some of the code from Mike Golds Exercise Tracker articale to print a report from a datagridview witch works fine.The trouble I am having is three of the columns have money values in them and they are formated to currency in the datagridview but when I print the report the three columns don't show as $1.00 but 1.0000.I am just learning C# and need some help to format the strings in the code to show the correct $ value.Hope someone can help thanks Barry
