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

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
