Horizontal Slider: Data-type-Error defining Minimum and Maximum

Hi,
for my actual GUI project I want to use a "Horizontal Slider" to change a variable value during simulation.
Now my problem: when I enter the value for the Minimum and/or the Maximum by defined variables, I get an error saying: "Enter a scalar numeric value for parameter 'Minimum'". The strange thing is that the right value for the variable is shown on the right side of the box, but is not accepted (see Figure).
How can I enter variables by not getting this error? I defined the minimum as "Minimum = 2000;". When I enter the value "2000" directly (not using the defined variable name), it is working.
Can anybody help me with this problem?

Hi,
The values for Minimum and Maximum need to be finite, real, double, scalar. They cannot be variables.
To learn more about the Horizontal Slider in Simulink, please refer to the MathWorks documentation link below:
