What have you tried so far?

Can you post your code ?

You may want to explain in more detail, what is your system doing exactly. Your description is  vague

The more information you can give the quicker we can help

Enter the desired number in the variable. Right click the numeric variable and select "Data Operations" --> "Make Current value default"...

Post if this is what you want.
