Confused about syntax

[Grinvald, Edward]

Hi,
i'm just slightly confused.
i have the following 'code:'
  <input
   message="Please enter the project you want to build:"
   addproperty="vssproject"
  />
  <input
   message="Checkout source from VSS?"
   validargs="y,n"
   addproperty="do.checkout"
  />
  <condition property="${vssproject}.checkout">
   <equals arg1="y" arg2="do.checkout" />
  </condition>

if i wanted to print the value of ${vssproject}.checkout (set/not set), how
would i do it?
${vssproject}.checkout 
or
${${vssproject}.checkout}
or
${vssproject.checkout}
 
Thank You,
