In yellow mark all the value are as i need it for deflection limit.

Just read the values in your input table, below your yellow cloud of first fig. This govern the design
DL limit, abs = 0.0254
Super DL+LL, abs = 0.0254 .....
It is in meter. (25.4mm)


You have to modify these values.
Regards,
Visu

Ratio , Absolute and Both ,So which is more important Ratio or Absolute deflection ?
