from your doc is difficult to guess, post all your script, if possible your qlik doc and excel files
it seems the excel file is missing
in your script you can use the following statement to know if the problem is after first, second or last excel load
here a video to get started with load from excel
here a doc on loading data
You tried with the table wizard but without success?
As Fernando already assumed, it seems that the excel file is not where QV expects the file to be.
In your LOAD statement, you don't specify the absolute path, so QV expect it to be in the same folder as the QV application (.qvw file) itself. Try specifiying the complete path or copy the Excel file to the same directory as your application is in.
Go to Start - Run , paste this "C:\Users\chevaf1\Desktop\images\GSR_SET6_DATA.xlsx" and see if the document opens. Either its not in that path , or you don't have access rights.
Try this to fix the issue
Create a new folder in your desktop and copy the excel files there. Create a Qlikview document in that folder and use the following code
(ooxml, embedded labels, table is Sheet1);
replace sheet1 with your sheet name if needed.
