CSS file issue for totals row

Dear all,

In our Design Studio (based on a universe DataSource) we use a calculated measure delta % which should be shown with a % sign.

I have added this % sign with the following code in my CSS file:

As it is impossible to let Design Studio calculate the measure for the totals row I had to select Calculate totals as: Hide for this measure in the initial view of the DataSource (so the values in the totals row for this measure = 0).  But due to the coding in my CSS file the % sign is also showing in my totals row.  Can I hide the % sign in the totals row only?

Kind regards,

Lieselot
