Hi there
I already opened up another topic about the nearly same problem. But to be honest, I again have problems with that sorting-function of my automatically created on basis of a sharepoint list.

I want to sort the gallery by the Company Name ("Firma") on the left side. In the sharepoint-list, the name of the column is also "Firma". But I cant change it properly in the formula of the gallery. Every time I do this, there are some errors as if it doesn't recognize that column name.

Any ideas? It should be so easy yet I don't know how to solve this.
