conditional statement gt not working with Slider

Code:

Code:
<setting label="34009" type="slider" id="sliderSmarti" default="0" range="0,10" option="int" />
        <setting label="34010" type="text" id="relais1" default="Relais" visible= "gt(-1,0)" enable="true" />
        <setting label="34011" type="text" id="relais2" default="Relais" visible= "gt(-2,1)" enable="true" />
        <setting label="34012" type="text" id="relais3" default="Relais" visible= "gt(-3,2)" enable="true" />

Small summary:

So I wanted a slider that has 0-10 values. If someone slides them to 1 than the relais1 should appear. But it does not work.

can someone help?
