Problem with programming Logo soft

[Breman]

Ok all you geniuses out there,
Please help a fellow out here.

Certainly a small problem (or none) for most of you, but for novis, a setback..

Installation:
a small, 3 level cargo-carrier up a hill.

One electric motor, two contactors (one for each direction of motor)

2 sensors per level (one extra for security) - Inductive

I have made the program, Ladder and FBD, in Siemens Logo software (the PLC is Logo).

The issue is when the “call-button” at the middle level is pushed, I can not implement in the program, that sensing if the “wagon” is up or down, which contactor to use, and using the sensors in the middle to stop.

I’m stuck..
