SQL Case Statement update

I am trying to update a field in my table but the case statement no matter what defaults to the else?   Can anyone help

declare @thckpsbeforE  decimal(18,4)  

update e
        thckavgmove    =  ((thckpspermove + thckmidpermove + thckoppermove) / 3),
       @thckpsbeforE  =  (ABS((thckpspermove + thckmidpermove + thckoppermove) / 3) * 100),
      e. thckpassastm     = (case WHEN @thckpsbeforE >= 40.0) then
from  table e

You've misplaced the ending parenthesis.  In the example above there should NOT be a close-paren after 40.0

You can't combine updating a table and updating a local variable in a single statement.

>case WHEN @thckpsbeforE >= 40.0
Also, SQL can't use the updated value in line 2 of an update in an expression in line 3.
You'll need to pull this off in back-to-back UPDATE statements.
