Expressions for time stepping are invalid

Hello
I keep getting the error "Expressions for time stepping are invalid" no matter how I try to change the information about the time steping. I am using the RF module, Time explicit
The expression I am using for the time steping is range(0,DT/24,5*DT)
What am I doing wrong?

Perhaps, DT has the wrong definition:
- or it is not time, [s]
- or DT is not Global Parameter
- or something else
In my models I have used, for example
In Global Definitions/Parameters
(Name)Dt (Expression)1e-7[s]
In Step1: Time Dependent/Times
range(0,0.1*Dt,Dt)
But I think the problem is in another place:
In Study 1/Solver Configurations/Solver 1/Time-Dependent Solver 1
- here check the section Time Stepping, namely, expressions for Initial Step and Maximum Step
- or it is not time, [s]
- or DT is not Global Parameter
- or something else
