Calculating different values depend choosing different values in listbox

[Anonymous]

Good day!

In my model i load data from excel file.

Then i calculate sum of fields (Weight, Volume l.) in one expression depend choosing value in list box.

When i choose 'Weight' - it's working.

But when i choose 'Volume l.' - calculating expression is not working.. I think, it's connected with 'space' in name of field Volume l.

Can anyone solve this problem?
