Hi @mahabbat
The issue can be resolved by reworking your calculations using the if functionality or the coalesce functionality as shown below
e.g. for If
(if(${crop1}=’’,0,${crop1}))+(if(${crop2}=’’,0,${crop2}))+(if(${crop1}=’’,0,${crop2})) + etc
e.g for colasce
coalesce(${crop1},0)+coalesce(${crop2},0)+ etc
This should sort out your issue with the blanks
Regards,
Stephane
