When you're putting data from designer section you need to add values separated by (,) comma.
The same thing is from blocks section.
When you want to set values from list.
or,
Did you want the SelectionIndex?
Or maybe the list block that looks up the index of some value in a list?
I would like to assign a value(integer) based on each list on the list picker. this is what I have on my elementsofstring. There are 5 items on that string.
Thank you!

Thank you very much for your help.
You could make two corresponding lists, or a list of pairs, or a dictionary, selecting the number value from the index of your text selection.
Thank you. Im new to MIT inventor. Can I get an example of the dictionary option?

You will need to set your blocks toolkit to Default in project properties
These are the errors made. I want to put the value based on the user preference in the blocks that I circled. But the app inventor read the key not the number value.
Did you change your blocks toolkit to default, and find the block you need ?
Have you built your app using my blocks? (do not set listpicker elements elsewhere)
You can create a variable to put in your formula, and set the output from the listpicker to the variable to then run the calculation
