Hi @mickaelschwedler,

It’s hard to decipher what exactly you are trying to do with “StartDowLocation” you don’t reference it anywhere apart from the MouseDown event. Why do you think you need a “Location” property - what are you trying to get from it?

Are you trying to do something like:

StartDowLocation.x = e.x;
StartDowLocation.y = e.y;

I think you’ll need to elaborate further for someone to be able to help you.

Regards,

Rob H

e variable location

var = e

Is this all you meant to post? I don’t understand at all.

e variable location

var = e

hi, I already corrected the error here is that at the time the code is too big and I wouldn’t be able to post it
