Trigger a workflow when condition is true but no trigger if it false

[Machingwa]

   

  I am trying to  trigger another workflow using this workflow  using Events.

1.This workflows checks in csv file  ,if  it has a '1' it process the macro which replaces the csv file with a '0' then  it triggers the other workflow..

This workflow is going to be scheduled every 10 secs on the server.

I do not want this to trigger the run of the other workflow if it is already running.

How do i accomplish that?

There is a "error tool" you might be able to use to throw an error and then you cancel the workflow on error so next one will no run? or do not run next workflow on error which is setup in your events tab.
