When I select the variables to print in the interactive simulation mode of OMEdit and then I press the Initialze - button, the following message appear in the OM Log:
  setfilter#1#tank1.h:tank2.h:source.flowLevel#end

-> In the setfilter- command there is "#" missing between Variables and Parameters . ( setfilter#seq#var1:var2#par1:par2#end). In the Variables - window you don't differentiate between Variables and Parameters. If the "#" is missing between Variables and Parameters , OMI assumes that  tank1.h,tank2.h,source.flowLevel are parameters and returns the values of the first three parameters, which doesn't fit to  tank1.h,tank2.h,source.flowLevel , because tank1.h,tank2.h are variables.

------
How does the parameter-window ( parameter change) work ?

Thanks.
Best regards.
