Read the Y of a layer

Hi,

I have a layer loaded at y=50 px at beginning and I try to move it according to his position.
The button has this action :

<action name="ShowHide">
if(layer[Mylayer].y == 50px,
tween(layer[Mylayer].y, 300px,2);				,tween(layer[Mylayer].y, -300px,2););
</action>

The first part didn't work, the second part work. I think the line "layer[Mylayer].y == 50px," is wrong.
Any idea ?


Thanks

Yes, it doesn't work either
Can I trace layer[Mylayer].y ?
Perhaps the datas is empty.
I don't know how to trace it.
Thanks

It's okay, the problem was the y_data. It came from a button who's in Mylayer and his y is 0 from the parent layer...

<action name="ShowHide">  showlog();
if(layer[Mylayer].y == -300,
tween(layer[Mylayer].y, 0px,2);
,		tween(layer[Mylayer].y, -300px,2);
trace('layer[Mylayer].y == ',get(layer[Mylayer].y));
	);</action>

Piotr, thank you for your help
