Serious problem peeps. And BAWMP!
Try this:
Make two bricks. Events for the first one:
>OnAcivate > Self > SetVariable > test, 5
Name that brick 'oo'
Other brick:
>OnActivate > NB(oo) > ifVariable > test, Equals, 5
>VariableTrue > Client > ShowMessage > CenterPrint, Yay!, 3
>VariableFalse > Client > ShowMessage > CenterPrint, Aww!, 3
Click the brick named oo, then the other one. No message is shown. Why?!
