Missing Script Input Type for Extension Attributes

[sgreilick]

When creating a new Extension Attribute, I don't have the option to set the input type to "Script" 
I've been trying to create a smart group based on "uptime," but each guide that I go over says to set the extension input type to "Script"
Am I missing something? Am I in the wrong place?
Thank you!

Be sure you're trying to create an extension attribute under Computer Management and not Device Management. Only computers support scripts.
