I have set up a simple array designed to take in file paths from the system.file.getTempFile() method which returns a string. However, when I attempt to run my script I will get an error that says “IndexError: index out of range: 1” and the error will point to the line printing out the array value (last line of code). I believe this is due to there not being anything with a value, or anything at all in the location of the array it’s being asked to print. Here is my whole script.

`CompanyGridData = event.source.parent.getComponent("companyDisplay").data
counter = 0
for counter in range(0, CompanyGridData.getRowCount()): #CompanyGridData.getRowCount() returns 3 and works fine
	tempFile = []
	tempFile.append(system.file.getTempFile(".jpg"))
	print tempFile[counter]`  
If you want a look at the actual error report, heres a link:

If anyone has any ideas as to why this is happening, please let me know.

Move your declaration of the tempFile outside the loop. Also, just to clarify, you’re dealing with a list here, not an array.

Thanks Kevin, looks so obvious now.
