Variable error - startup

Hi,

Hopefully a simple question… I receive the following error on a workflow from latest version (5.3) workflow…

WARN Excel Reader 5:1 Errors loading flow variables into node : Errors overwriting node settings with flow variables: Unknown variable “Path”

It’s a simple workflow where I scan a directory of excel files and loop through and to read/process them. I’m using what I believe to be a flow variable to pass from the Table Row Variable Loop Start to the Excel Reader.

While the flow works when I try to use in a batch file it gives me an error about path variable.

I’m just a little confused about how to use flow variables. I have watched the videos/read similar topics but am confused how to proceed to correct the error(s). As I said the flow works interactively but when trying to run from a command line errors giving an error about Path. Do I initialize a Path variable being empty so in the workflow it can use it?

Thanks for any insight.

Jeff
