Scala - error: recursive variable name needs type

I'm using an older version of scala 2.7.5

When i try to do computations like this,

var x = 100

var x = x%1000

I get a

error: recursive variable x needs type

Is there a work around? why do i get this error?

For anyone still wondering, in this particular case Kim Stebel already wrote the correct solution. If you just wanted to solve the type error for var x = x%1000 the solution would be simple like this: var x:Int = x%1000 (which equals to 0, because of the default int value of the JVM, this is a really weird recursive expression though)

You're declaring the variable twice rather than just changing its value. Instead, do

var x = 100
x = x%1000
