No error messages in the output, but this GUI script will not work. Why? (Local Script)

Whenever I run this script and type in all the variables, the script breaks and doesn't output an error message. Any help or suggestions?

frame=script.Parent
lp=game.Players.LocalPlayer
submit=frame.submit
value=frame.value
stat=frame.stat
player=frame.player
admins={
    ["XtremeSpy"]=workspace.ec.Value, --Int Value
    ["Frosty"]=workspace.fs.Value --Number Value
}
groupid=0 --I changed it to be anonymous 
function isPlayerAdmin(p)
    for i,v in pairs(admins) do
        if p.userId==v or p.Name=="Player1" then --Player1 to studio test it
            return true
        elseif p:IsInGroup(groupid) and p:GetRankInGroup(groupid) > 11 then
            return true
        else
            return false
        end
    end
end

function checkStat(stat)
    types={
        "Kills","Deaths","Points","Demerits","Promotion" --Promotion is Bool Value the Rest are int values
    }
    local check=stat:lower()
    for key,value in pairs(types) do
        if value:sub(1,check:len()):lower()==check then
            return value
        else 
            return false
        end
    end
end

function getP(name)
    local p1 = name:lower()
    for i,v in pairs(game.Players:GetPlayers()) do
        if string.sub(v.Name:lower(),1, string.len(p1)) == p1 then
            return v
        else
            return false
        end
    end
end

submit.MouseButton1Down:connect(function()
    if isPlayerAdmin(lp) == true then
        if string.len(value.Text) > 1 and string.len(stat.Text) > 1 and string.len(player.Text) > 1 then
            if tonumber(value.Text) ~= nil and checkStat(stat.Text)~=false and getP(player.Text)~=false then
                local vlu=tonumber(value.Text):match("%d+")
                local sts=checkStat(stat.Text)
                local plyr=getP(player.Text)
                game.Players[plyr].leaderstats[sts].Value=vlu
            elseif tonumber(value.Text)==nil and checkStat(stat.Text)~=false and getP(player.Text)~= false then
                if value.Text:lower()=="yes" or value.Text:lower()=="no" then
                    local vlu=value.Text
                    local sts="Promotion"
                    local plyr=getP(player.Text)
                    plyr.leaderstats[sts].Value=vlu
                end
            end
