Using a variable created in a GUI

Hey guys,

 

I've created a GUI where the user can choose if he wants to apply a pressure load in x-, y- or z-direction by clicking on a button. By clicking on one of the buttons, a variable called 'vector' will be created.

This variable should later be used in the command that creates the load.

 

Trying to select this variable with $vector on the position that is marked in yellow in the end of the screenshot, nothing happens.

 

Could you somehow help me out with this problem?

 

 

Kind regards

Simon
