Help Understanding a expression

Hi All,

I am new to qlikview .I am loading month into ListBox. The months were not displaying in proper sequence so i did some googling and got the below expression,

=match([Month Name],'Jan','Feb','March')

The above expression work for me and months were displayed in Jan,Feb,March.... i.e. as expected.

When i tried to figure out what does the expression means, the function "Match" according to qlik.com returns  "returns the number of the expression that matches".

Now i am not able to figure our the logic, match returns a number of expression that matches but how could that sort my items in ListBox.

Re: Help Understanding a expression

So based on your dimension value, the number is assigned to it and that number is used to sort the list box.

=Match([Month Name], 'Jan', 'Feb', 'March')

will assign Jan = 1, Feb = 2, and March = 3 and this 1, 2, 3 are used to sort your list box based on ascending/descending order you choose.

Is this what you wanted to understand?

Re: Help Understanding a expression

This is what you need then

=Match(Only({1} [Month Name]), 'Jan', 'Feb', 'March')

The issue is that as soon as you select a particular month, the Month Name function only shows that particular month and then everything else become a 0. Adding {1} ignore any selection and your sort order stays intact.

HTH

Best,
