Help with my code - transfer information between Visualforce and Controller

Hello everyone...

I'm working now in a complex part of my developing app, which is a full custom code, so that I will try to do is:

- Compare 2 variable; 1 from a pick list field (Width), and the other one from a field (Max_Width)

- Get 3 types of result:

  * Width > Max_Width; pop up a message to avoid create the record "Please pick width less than Max_Width"

  * Width = Max_Width; show a section with two fields Long_Imperial(number) and Length_Units(picklist field)

  * Width < Max_Width; show a section with standard pick list length

I've developed this code below, but I have no idea how transfer data in between them... Can somebody show me some light or help me with this code?, I don't know, whether it is possible that I'm trying to do, or not...

Thanks in advance, any advice it will be welcome

                                rendered="{!Customer_s_Price_List__c.System_Of_Measurement__c == 'Imperial System'

                                && ( Customer_s_Price_List__c.Product_Type__c == 'Fabric' || Customer_s_Price_List__c.Product_Type__c == 'Tape') }">

    You need to grab the record from the page in the controller in the constructor method.

    public with sharing class testme {

    private final account vfRecord ;

    public testme(ApexPages.StandardController stdController) {

    this.vfRecord = (account)stdController.getRecord();

    }

    If you still have issue, post the whole code.

    thx
