I dont quite understand how the Parameter function works in QS

I have two formulas

Days = Param("Days", 252, 504);
Plot(beta(close, GetSeries("SPY", close),Days), "beta", colorRed|55|colorRed|64|0, ChartBar, StyleOwnScale);

and

Plot(beta(close, GetSeries("SPY", close),252), "beta", colorRed|55|colorRed|64|0, ChartBar, StyleOwnScale);

Why do I get different values on the chart?

Also,how does one adjust the value for the parameters on a chart?

I dont see a slider or input box.

Thanks,

Allan

I see by right double clicking the pop up box comes up..
What is confusing to me is the wording of Default vs Value..

It appears you chart the value for Value

What do you mean by Default?

"Param" function is no longer necessary. You can dynamically update values without using "Param" function.
