How to set range var "time" in ADS?

When I used ADS to analysis, it always said some errors as attachment:
it seems that the "rangevar" can NOT be directly set to "time", how to set it?
I also attached the ADS sch file for ref.
Many thanks.

Define a independent variable-for instance- "mystoptime" and assign a number for this variable after that put this variable in "stop time" ( or wherever you wish).Yield controller will change this variable in each iteration and you will get the results regarding this variations.
