problem with excel invoke node

[kashifsherwani]

hi,

I am getting the below error.

what I am doing is reading the excel file from two different locations using for loop. In the first cycle, the program runs fine but in the second cycle, the program gives this error because of the file in different locations. 

I am getting the workbooks invoke node output 0 in the second loop.

Looking forward for some help.

Thanks

Hi kashifsherwani,

please try to close all those references AFTER you did all the work in the loop…
