[JavaScript] for loop *RESOLVED*

my code:

VB Code:

function checker(){
    var complete = "F"
    
    for (i = 0; i <= count - 1; i++){
    
    if (document.pc_app.F_PROF_1[0].checked || document.pc_app.F_PROF_1[1].checked || document.pc_app.F_PROF_1[2].checked || document.pc_app.F_PROF_1[3].checked){
    complete = "T"
    }
    }

F_PROF_1
F_PROF_2
F_PROF_3
