In a total, @ displays the value of the data
For example, if a total is specified for the Region column, and you enter the following text into the Caption field for the total heading:
All values in the @
the total heading would display the following text for the Western Region:
All values in the Western Region
To display the @ symbol, you must enclose it between two quotes such as “@”.
The double quote syntax is not limited to a single character. In general you can use a backslash escaped string inside double quotes. For example:
"1234567890\\abc\\d\"x\"yz!@#$%^&*()-+=_{}[];:'|?/><,.` ~"
is displayed as:
1234567890\abc\d"x"yz!@#$%^&*()-+=_{}[];:'|?/><,.` ~
