Pre populating text box control on custom UDI page with the MACAddress task variable

[Dsbloom]

Hello,

 

I am trying to create a custom page for my UDI wizard, and I need to prepopulate some of the controls with information about the machine (MAC address, for example).

 

I am very new to this, so how do I go about it? Do I need to specify the task variable in the customsettings.ini?

 

Thanks!
