set a variable in mutliple places in a master page

I am trying to grab a string of text from the .vb file of my master page. I need to render this text out as part of the class definitions.

E.g. <div id="######ContentArea">

I need to replace the ###### with a string I have cr开发者_JAVA百科eated in the .vb file.

How do you do this? Or is there an easier way = NEWBIE here!

If you need to make this change on enough pages, you should consider removing that div from the master page. Otherwise it would be helpful to know exactly what you are trying to do and why you are trying to do it that way.
