I have an Excel Sheet containing a list of malls.

When I use the Wizard data import function selecting the PushPin view, everything is ok and I see ONE pushpin for EACH mall.

But, When I want to use the Multiple symbol function, to sort the malls by size for example, I force to choose a "show the data by" level (street, municipality...).
And, anything I choose, the number of values mapped is lower than with the pushpin's view.

I don't want to use "the show the data by" function....How can I do it ??

Thanks for your help and sorry for my French English
