Slice with lookup function in row filter expression

and([pest]=LOOKUP(“1”,“choose pest”,“match”,“pest”),[crop nr]=lookup(“1”,“choose pest”,“match”,“crop nr”))
This formula is correct according to the expression test.

But when this slice is used to filter data in a chart, the chart returns empty and says “no data available”.

I want to use a detailed view where 2 columns are shown from table 1 to slice table 2 with data to show in a chart.
How to make a working row filter expression for this?

Would you please check first that the slice is working correctly for example with the table view.

I tested it,
When the expression = “text” is used, the slice works and data is shown in the chart.

May I ask what do you mean by "Expression = “text”

sorry, when the expression is [pest]=“macrolophus” the slice works for the chart.

When you use and([pest]=LOOKUP(“1”,“choose pest”,“match”,“pest”),[crop nr]=lookup(“1”,“choose pest”,“match”,“crop nr”)) with a table view, does it show that table view correctly?

and([pest]=LOOKUP(“1”,“choose pest”,“match”,“pest”),[crop nr]=lookup(“1”,“choose pest”,“match”,“crop nr”)) shows an empty view, no data in it.

If you check your data source directly, do you see any record where these two evaluations are both correct?
