Help with "For" Loop... Not Checking All Boxes in Array

Hi there - apologies for the confusion - I tried to only show the most relevant areas of the code and in so doing didn't fully explain that I already have "KPOR" chosen as a location in my document while I'm testing in the console. The results are the same no matter which location I choose - only one box gets checked (either ME_1, NH_1 or VT_1).

All state specific fields (which consist of both checkboxes and buttons) are hidden prior to choosing a location, and need to be toggled to "visible" / toggled to be checked if they are checkboxes. I start by hiding all the state fields and unchecking all boxes - just in case something has hiccuped up until this point - then displaying/checking only the fields that pertain to that state.

Here is the entire snippet...

var Location = this.getField("LOCATION").value;
var MEHead1 = this.getField("ME_HEADER1");
var MEHead2 = this.getField("ME_HEADER2");
var MEForms = this.getField("ME_FORMS");
var ME1 = this.getField("ME_1");
var ME2 = this.getField("ME_2");
var ME3 = this.getField("ME_3");
var ME4 = this.getField("ME_4");
var ME5 = this.getField("ME_5");
var NHHead1 = this.getField("NH_HEADER1");
var NHHead2 = this.getField("NH_HEADER2");
var NHForms = this.getField("NH_FORMS");
var NH1 = this.getField("NH_1");
var VTHead1 = this.getField("VT_HEADER1");
var VTHead2 = this.getField("VT_HEADER2");
var VTForms = this.getField("VT_FORMS");
var VT1 = this.getField("VT_1");
var VT2 = this.getField("VT_2");
var allFields = [MEHead1, MEHead2, MEForms, ME1, ME2, ME3, ME4, ME5, NHHead1, NHHead2, NHForms, NH1, VTHead1, VTHead2, VTForms, VT1, VT2];
var allChecks = [ME1, ME2, ME3, ME4, ME5, NH1, VT1, VT2];
var StateFields = [];
var StateChecks = [];
//Loop through fields and push to new array depending on state chosen
for (i = 0; i < allFields.length; i++) {
    if (Location == "KPOR" || Location == "KBAN") {
        if (allFields.name.indexOf("ME") !== -1) {
            StateFields.push(allFields);
        }
    } else if (Location == "KCON") {
        if (allFields.name.indexOf("NH") !== -1) {
            StateFields.push(allFields);
        }
    } else if (Location == "KBUR" || Location == "KRUT") {
        if (allFields.name.indexOf("VT") !== -1) {
            StateFields.push(allFields);
        }
    }
}
for (i = 0; i < allChecks.length; i++) {
    if (Location == "KPOR" || Location == "KBAN") {
        if (allChecks.name.indexOf("ME") !== -1) {
            StateChecks.push(allChecks);
        }
    } else if (Location == "KCON") {
        if (allChecks.name.indexOf("NH") !== -1) {
            StateChecks.push(allChecks);
        }
    } else if (Location == "KBUR" || Location == "KRUT") {
        if (allChecks.name.indexOf("VT") !== -1) {
            StateChecks.push(allChecks);
        }
    }
}
for (i=0; i < allFields.length; i++) {
    allFields.display = display.hidden;
}
for (i=0; i < allChecks.length; i++) {
    allChecks.checkThisBox(0,false);
}
for (i=0; i < StateFields.length; i++) {
    StateFields.display = display.visible;
}
for (i=0; i < StateChecks.length; i++) {
    StateChecks.checkThisBox(0,true);
}
