var dropboxleft=425 //linker positie (in px)

var dropspeed=45 //snelheid verschijnen (groter is sneller)



//er zijn 3 verschillende weergaven mogelijk:

//1) "always"- drop box zal iedere keer verschijnen bij het laden van de pagina

//2) "oncepersession"- mbv cookies zal hij slechts eenmaal verschijnen

//3) integer (ie: 5)- variabele weergave, zelf in te geven

// bijv, 2 laat de box (1/2) 50% van de keren zien dat de box verschijnt.
