EllipticTheta[3,real,Exp[I real] ]

 Hi MathGroup,

 I have a problem with EllipticTheta[3,...].
 For Propagators in quantum mechanics one needs
 EllipticTheta[3,position,Exp[I time]]
 where position is a real variable and time also.
 But the Theta-function  with an third argument of 
 absolute value unity are not evaluated to a number.
 Can I force Mma to give a number as a result??

 I am something missing concerning convergence?

 Thanks for help,

 Michael Trott
