How to script in Flow Designer

[ceraulo]

Hello!
I've recently started using the Flow Designer to create workflow for our Catalog Items.
In the traditional workflow, customizing the Short Description is shown below.

task.short_description = current.variables.variable1 + " - " + current.requested_for; 

In Flow Designer, I tried the below but it does not work.

var shortDesc = fd_data.trigger.request_item.variables.variable1 + ' - ' + fd_data.trigger.request_item.requested_for;
return shortDesc;

Please help!

Thank you.

Marked this helpful. (I wish it was easier to find direct how-to-script-stuff-in-flow answers like this.) I needed to know this trick, but for a different application, where using the 'Get Catalog Variables' pill picker was not an option. Thankee sai.
