I have a lamp with two switches installed wrongly as:
---[ ]---[ ]----( )---
Sw1 Sw2 Lamp
How do I fix it into a threeway like your pic? Do I need to pass more wiring? (it's a rental, if I can fix it simply by reconnecting stuff on the switches, I might do it, but if I need to actually put down some wires (like blue/purple on your pic), I don't care that much, I'll leave it as is)
