Combo Chart won't Filter correctly

[giasinga]

I am new to Qlik Sense. I hope you can understand my Question.

So I want a Combo Chart with stacked values. Right know I have this chart:

It is working fine but I really want to have the Chart stacked. Like this:

The Problem with the second combo chart is that it wont Change when I am using a Filter.  

Ideally I would like it to only show me a green bar when I am Filtering for product_cost5

My formula for product_cost1 is:                                sum({<[type]={'product1'}>}cost) 

same with the other ones except the           'product2'          'product3'              'product4'               'product5'

I hope I made the question somewhat clear.

Hello, Giasinga

Can you try this expression

sum({$<[type]={'product1'}>}cost)

Hello Tomovangel,

I have already tried that way. It does not make a difference after using the filter.

[tomovangel · Accepted solution]

then can you try to write the expression in If 

like 

Sum(if(type='product1',cos))

Yes that is the correct one. 

Thank You very much
