I currently start using TopRank at school and find it annoying to relaunch Excel and Toprank after an error occured. Errors mainly show up when I edit values "Step through Input cells". Even when I master to run the What-If analysis, at least there I get the error 20034:6 and no data.

I will attach my file, that should analyse cell C27

Does anyone of you has a clou how to avoid this?

Thanks in advance.
