I ordered the SFH 485 P leds but i'm having problems with the wizard, I don't know if I should input the values with " . " or " , " in Power Supply -> Voltage Value (V) and in Led -> Forward Voltage. Since getting it wrong screws up the whole thing it seems important to know. Also, if for example i have 2 rechargable batteries (1.2V) should i add them? Would it be 2.4V? Supposing it is so, would these be the correct values? Voltage Value (V): 2.4 Forward Voltage (V): 1.5 Forward Current (mA): 100 Also i read some of the guides on the forum and the most don't check against the wizard.. I'm really stuck with this resistor thing. Any help is largely appreciated.

When I wasnt sure if the free track wasnt reading the IR lights, I pulled out the old camcorder with nightvision to troubleshhot.
