i new javascript , working on fallible pdf form , trying set multiple things. first need compare user entered date current date see if withing 5 years day. second thing need change fields background color if date @ 5 year time or outside of range. code have been trying hasn't worked far. there 37 fields need checked this.

for(i=1;i<38;i++){  var y = d.getfullyear();  var d = new date(); var m = d.getmonth();   var d = new date(); var d = d.getday(); //n =2  var strdate = this.getfield("text"+[i]).value; var arrdate = strdate.split('/');  var month = arrdate[0]; var day = arrdate[1]; var year = arrdate[2];  if(year+5>=y){ if(m<=month){ if(d<=day){ this.getfield("text[i]").fillcolor=color.red; }}}}
