Field control with minimum and maximum

[Edward]

I have a variable which I want to be controlled by 2 controls, a field and a slider control.
The slider control can be given a minimum and a maximum value. This is what I want.
To give the user the opportunity to give the variable an exact value, I have also introduced a field control. The problem is that the field control can't be given a minimum and a maximum value. I can use code to check the value, but I don't know how to undo the new value.

Anyone an idea to get this working?

if the variable is f, and the minimum and maximum you want is fmin, fmax
You can add the following to the action field for the numerical input textfield element

if(f<fmin)f=fmin;
else if(f>fmax)f=fmax;

Is that the logic you want. Just try to express your login into formula/equation.

Yes, this is what I wanted.
Thanks for this very simple solution.
