Demantra client and server expressions

Hi,

We have configured a client expression and server expression for calculating a plan revision based on the calculated forecast/override and rollover forecast from the previous bucket. I am able to see the calculated value in the worksheet once I override the forecast.But after saving and rerunning the worksheet, the number goes away. But the same number is stored in backend. I am able to query and see it. Can someone help me in solving this issue

Thanks
