Update drop down selection from User Input file

[varunamin]

Hi,

I am trying to populate the drop down list from the file that user uploads. Current analytic app provides a drop down list form the previous generated list and not the current file being uploaded.

I read that chained app should be used. But I am unable to use it.

Please provide any solutions.

Thanks!

Thank you Mark!

That really helped. But I am stuck in selecting the record from the drop down list.

App 1:

App 2:

Excel file 2.xlxs goes into the drop down. The list gets generated. But when I select one record from the drop down, it does not fetch any record from Excel file 123.xlxs.

Thanks!
