SSRS 2008: Count alphanumeric characters in a field

I have a SSRS 2008 report.
I have a textbox that holds the customer name.
If that customer name has more than 50 alphanumeric characters in it, I want to change the font size in that texbox to 6.37pt otherwise i want it to be 6.5pt.
Can this be done and how ?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

in the property box for font size, create an expression, which will say =iif(LEN(Fields!dataset.item.value) > 50, "6.37pt", "6.5pt")

I dont actually have the tool open, so I think maybe some of  this syntax is a bit off, like the fields.dataset.value, or the font size. but all the pieces you need are in the expression builder.
