Percentage in simple table

[#1]

Hi everybody,

I need to calculate the percentage of every line (Key %) over the total of 'Key Vir', for example 315.11/709935.

I use the expresion $(vFinanceKeyVirMain)/sum(Total $(vFinanceKeyVirMain)) where vFinanceKeyVirMain is the value of 'Key Vir' for each line and it is calculate with sum({$<[Invoice Date num]={'>=$(vDateMin)<=$(vDateMax)'},[Transaction Type Main]={'Online'}>}[Total value]) expression (that it works fine), but unfortunally it doesn't works as you can see in the image.

Any idea?

Thanks in advance.
