Dear all,
I am trying to use the periodic run to read from external text file and write to the same. but it only read/write at 1st run. any idea !
Regards,
Mohammad Nawar
Add a node that will refresh (date time now), and use that to trigger a recalculation of the file name to cause a refresh of the nodes downstream.

Can you show me an example how to refresh the node since it does not have input. l am a little lost 
In a code block
{ filePath, dateNow }[0]

If you are running Dynamo 2.0, lists were changed to brackets instead of {}. Try [ filePath, dateNow ][0];

Thank you all
Side-note… If the workflow you are showing here is what you’re doing you should add a “[Waitfor,pass][1]” in between filepath and writetext as you want the rest to complete before writing back to the file!
