Error Occured Problem

[Jnkansayeboah]

Hi All,

I am new to QlikSense. I am trying to merge three different data sources together. When I click "Load Data" I get the messages:

"The following error occurred:  -129 = " 

"The error occurred here: ?"

I am not sure what this message means and how I should interpret it. I have attached images of my code and the error message. Can anyone help please?

Thanks!
