Graphical CV Range variable in the filter expression

Hello,

I'm building Graphical CV with Variables. I created a variable from type is "Range" (or "Interval")

I can use this variable in the provisioning in the filter expression but how can I use the TO\FROM of the range (or interval)?

The VAR VAR_BA1_C55POSTD is from type range when I use from\to I get no result. What should I put instead?

Thanks,

Amir
