need some EL help please

The following "works"

Volatility(Length); or Volatility(Length) of data2;

However, if I want to use the same function to find the Volatility of a
variable I can't work out the syntax. For example, the following doesn't
work.

Volatility(Length) of value1; {where value 1 is the Sumlist of data2-10}

Thanks in Advance
