Script que ne se lance plus

Bonjour,
Je vous explique mon problème, j'ai fait un petit script pour qu'il me calcule automatique le total de nombre d'heure par semaine.
lundi + mardi + mercredi + jeudi + vendredi = total
Mais il ne se lance pas depuis la présence d'autre script qui marche eux par contre.

function controleh() { 
var variable1 = document.controleChamps.hlundi.value;
var variable2 = document.controleChamps.hmardi.value;
var variable4 = document.controleChamps.hmercredi.value;
var variable5 = document.controleChamps.hjeudi.value;
var variable6 = document.controleChamps.hvendredi.value;
if(variable1 !== "" && variable2 !== "" && variable4 !== ""&& variable5 !== ""&& variable6 !== "") { 
   var variable3 = Number("variable1") + Number("variable2") + Number("variable4") + Number("variable5") + Number("variable6");
   document.getElementById("total1").value = variable3.toFixed(2);
} else {
   document.getElementById("total1").value = "0";
}
}
