Alert on a page to upload size.

Hi Team,

I want to fix this by adding an alert message on my VF page when the upload file size is not more than 25MB. it should show the alert wherever the uploaded file is more than 25MB.

Here my vf page,

Unsure why not working

Working on a Rock Paper Scissors game to learn Apex/visualforce with (and to be able to play with other devs on the org). Somewhere in the main body, something is not working right. It is running, that much I know, but somewhere down the line it is not updating the page nor the database as to the result. Here is the VF page:

 

<apex:page showheader="false">
<c:rps ></c:rps>
</apex:page>

 

Here is the Component:

 

<apex:component controller="rps" allowDML="true">
Lets play Rock Paper Scissors!
    <apex:form >
        <apex:selectList id="rps" value="{!input}" size="1" title="Choose Your Weapon">
            <apex:selectOptions value="{!inputSelect}"/>
        </apex:selectList>
        <apex:selectList id="rps2" value="{!partners}" size="1" title="Choose Your Weapon">
            <apex:selectOptions value="{!partner}"/>
        </apex:selectList>
        <apex:commandButton action="{!makeNew}" value="Create Game"/>
        <apex:commandButton action="{!makePlayable}" value="Allow Multiplayer"/>
    </apex:form>
    <apex:form >
        <apex:pageBlock >
            <apex:pageBlockButtons >
                <apex:commandButton value="Play" action="{!processSelected}" rerender="table"/>
            </apex:pageBlockButtons>
            <apex:pageBlockTable value="{!ListAvailable}" var="a" id="table">
                <apex:column >
                    <apex:inputCheckbox value="{!a.selected}"/>
                </apex:column>
                <apex:column value="{!a.game.Name}" />
