I need help in refreshing one panel whenever the button is clicked

[mee82]

Hi...
I have three panels.In the top panel there is one label,one textfield and one button.On click of that button it will verify the textfield.If the value in the textfield is a valid one it will display a table in the second panel or else a label in the second panel...but my problem is that whenever the button is clicked a table or a label opens depending on the textvalue....whereas the panel has to get refreshed when the button is clicked....Any suggestions..
Following is the code
