Passing variables

Hi there,

I feel really stupid to ask this, but here we go.
I want to pass custom variables from UI++ (put as a prestart command) to the task sequence.

The pass xml part is as follows
<Action Type="TSVar" Name="OSDComputerName">%MachineName%</Action>

<Action Type="TSVar" Name="Model">%Model%</Action>

<Action Type="TSVar" Name="LocalAdmin">%XAuthenticatedUser%</Action>

When I use CTRL+F2 these (before pass)variables are looking good but the condition during the task sequence is just ignored
(i'm pretty sure i'm missing somewthing obvious here)

Task Sequence as follows

any ideas?

Cheers!
