[moudjibb]

Hi all,

I am new to ServiceNow and I and struggling with an issue on Zurich edition. I am currently  following this exercise but unable to complete it because the get an error with I try to create an input variable. I get the error message try again. 

To replicate this on Zurich release,

1. Go to   SERVICENOW APPLICATION DEVELOPER - Developing for Flow Designer -  Exercise: Create an Action 

When you try to complete this part . 

"

Add a property_name input variable.

1. In the Input Variables section, click the Create Variable link."

The error try again shows up.

The issue was the browser, I changed from Safari to Chrome and it worked.
