Setting bounds on all variables

Q: I have 4 variables. x (binary), t (continous), p (continuous) and Z (objective function) and set:

  
t.lo = 0;
t.up = 14;
p.lo=0;
p.up=1;

but BARON says I still did not give bounds for all variables. Why do I get this message even I bound my all variables (I get this message even I set bound for binary variables). BARON requires bounds on all expressions in your model. Sometimes the bounds on the variable still allow expressions to be unbounded (e.g. 1/t). We also made the experience that expressions even if they are bounded but become very large (1e7) are reported this way. If the problem persists, please email the model to support@gams.com.
