error 1 occurs at open file+.vi in labview 8.5

Hi,

I keep getting an Error 1 message whenever I try to run a part of this program. The program is very large but the problem is concentrated to a specific part in the IPCE case where I try to read from a file that is already saved on the computer. Essentially, I run the IPCE calibration once, save the calibration data and then run the program again only this time selecting IPCE instead of IPCE calibration. It is supposed to read from the reference spreadsheet I have already saved as well as the newly saved calibration data but Its telling me that the path is an invalid input. This is confusing since I can see the files right there, saved where they should be. Originally I thought it was a formatting error on my part but I have tried several different configuratins with no luck. Any help would be appreciated.

I have attached the program as well as the reference data that is already saved.

Thanks in advance
