Top N slicer define issues

the first problem is simple.

selectedvalues([value],100) means that if Values are not unique，if will return 100, now you don't filter your [value],so it's value is from 1 to 100, so the function will return 100

You should put [value] in the slicer, here i choose 5, [value] has only one value,

so the selectvalue() will return 5,not 100

and the rank <=5,will return 1 ,just likes the picture.

can i see your all function?now i can't know the answer of your second question.
