You probably don't want to set the variable's Calculation Type to "average". Set it to "Nothing" instead, otherwise all your caluclations will be averaged over "the number of records processed so far".

 

 

And I reckon that the result should be a Double:

 

 

new java.lang.Double( $F{total}.doubleValue() / ( ( $P{toDt}.getTime()-$P{fromDt}.getTime() ) /864000000 ) )

 

 

Use the Text Field's format string to truncate the fractional part to the number of digits you want to display.
