about player position variable and image positioning

hello there,

as stated above I have a problem with picture positioning in rm2k .
I have not too much experience with the use of variables so far. What I try to achieve is having a custom menu picture appear every time in a fixed position close to the main charackter. I found out how to make the programm store the hero's position in a variable. What I don't get is how to make my picture appear on or near these stored cordinates. If. I choose 'variable' in the picture menu the image kinda is connected to my xy-cordinates wich I can tell since it appears in different spots when I move. It's still nowhere near where I am standing a the moment when I opened the menu, but instead close to the upperleft corner of the sceen - even if I am in the opposite corner of it.

I read something about adjusting the variables somewhere but couldn't find out how I actually do that and what exactly I have to do. Hope somebody is able to help me.

Hope somebody can help me.

Don't use hero X and hero Y, but hero Screen x and hero Screen y.

Thanks. That worked.
But how can I adjust that variable now?

If I open my menu now it appears right above the hero but instead i want to have it a bit more to the top. Guess I somehow have to change that stored player screen variables but how?
