Vector3.new doesn’t read variables?

I want to create a tool that makes a part each time the player clicks.

I already a script that finds the position value of the tool, but the problem is that it’s in a argument, because I have to send to a remote event to instance it in the server, so everybody can see it, not just the player.

The problem is that Vector3 doesn’t accept variables, only numbers. So how would I convert it?

I need your help, thank you.
