You could use the "Mod" function that returns the remainder after a number is divided by devisor.
The following calculation will return 1 for an uneven $$value and 0 for an even $$value...
Mod ( $$value ; 2 )
You can replace $$value with any number you like to use this calculation on. The following will for example will return 1 for an uneven record number and 0 for an even record number...
Mod ( Get ( RecordNumber ) ; 2 )
Hope this helped,
Thanks, that's perfect. so many functions to learn
