Error in Moving load generation

Question

I have attached my STAAD 3D model with a moving load generator which when run is giving me an warning message. The warning message reads "No Members in specified Vertical Range". The moving load is being applied to level and straight beams. 
 Top Module - Platform.std Can someone please provide some guidance? Thanks.

Seems to be a precision related issue. The actual Y coordinate at the top of the structure is 8.2864 m (check the input file for the actual Y value), while in the moving load generation you are using a value of 8.286 m of the initial load position at y coordinate. Change that value to 8.2864 m and these warnings should disappear.
