Bouton control bouton

Hello, I would like to create a button which manages several parameters. I am encountering a problem, if I put a button on frequency I can control eq, filter but I can not control a parameter which is in percentage. I tried to create a button by parameters and a main button to link them together with knob1.setvalue (value); . the buttons move but do not activate the parameters. some help?

local perc = (value  component.get("min"))/((component.get("max")  component.get("min"))/100);

@Lindon
I don't understand where I should put this line and what it corresponds to. my konb 1 goes from 0 to 100 and my knob2 from 20 to 20,000. 
@yall so you want to use one knob to control two parameters:
your knob goes from 20 to 20000 (so its all set up for frequency
but you also want to control a percentage somewhereinline function myKnobControl(component, value) { local perc = (value  component.get("min"))/((component.get("max")  component.get("min"))/100); myFX.setAttribute(myFX.frequency, value); myFX.setAttribute(myFX.percentage,perc); }
So what we are doing here is working out what 1% is as a value and dividing this into the range returned..
So we are scaling our returned value to the range 0100, you can scale to other ranges too as required.

@Lindon said in Bouton control bouton:
myFX.setAttribute(myFX.frequency, value);
myFX.setAttribute(myFX.percentage,perc);it is beyond my skills ^^

@yall  its going to be hard to give you more of the answer without doing it for you.
