Easy php poll code check and message display problem

Hi,

I have made a php poll based on the same type at www.flashkit.com 

Example pages:
http://www.flashkit.com/tutorials/3D/
http://www.flashkit.com/tutorials/3D/Pseudo_3-Cort_Stu-104/index.php

My problem is simple, when the user click the submit button on one of the tutorials to cast a vote. The page refreshes and their vote is added but the voting table doesn’t disappear to stop them voting again. You have to go back to the main tutorial list page and then open up the tutorial again before you see the "you have already voted" message. So my question is this when the user votes how can I get it to display a message replacing the voting table that says "Thank you for your vote" and when you next visit the tutorial I displays you have already voted message?

Also would some one please check my php code and tell me if it’s correct as I am not sure the Rating_Functions.php code is right ???

Is this part right for instance: if (  $tmpDec[$loop] >= 10 ) {  ($tmpDec[$loop-1])

Could you please check the Rating_Functions.php code and tell me if its all right as well as help me get it so when a user submits a vote there is a message displayed when the page reloads saying “thank you for your vote”. Also when ever you revisit the page you get the normal “you have already voted message”

Any help would be appreciated
