Lets say that I have list of choices called "Source1", "Source2", "Source3", "Source4" and "Source5" in my combobox. When I choose "Source1", I want that the value of my label1 to set to 100. When I choose for example "Source1" and "Source2" I want to have 2 labels where label1 will be 100 because I have chosen source1 and label2 will be 200 because I have chosen also source2.

I tried to do it changing OnChange property of the combobox, putting here next things

UpdateContext({ItemVal1: If(chbsources.Selected.Value= "Source1";100;0)});;
UpdateContext({ItemVal2: If(chbsources.Selected.Value= "Source2";200;0)})
where ItemVal1 is text value of label1 and ItemVal2 is text value of label2.

But I didn't get result that I want.When I chose Source 1 and Source 2 I wanted to have 2 values where label1=100 and label2=200. But I got label1=0 and label2=200. How can I do it?

@akmaralnassir In a Combobox when you want to check for ALL selected values, you must use chbsources.SelectedItems property. Because you are using chbsources.Selected.Value, it will check only the last selected item. Change your formula to,
UpdateContext({ItemVal1: If("Source1" in chbsources.SelectedItems;100;0)});; UpdateContext({ItemVal2: If("Source2" in chbsources.SelectedItems;200;0)})
Hope that helps.
