How to assign Mathcad prime 2.0 output value to creo parametric 2.0 model as parameter?

Hi...

I have two questions as below,

1. How to assign mathcad prime 2.0 output value to creo parametric as a model parameter ?

2. How to integrate mathcad prime2.0 worksheet with creo parametric2.0 with output value type as a string?

I have integrated my mathcad worksheet with creo parametric but unable to make its model parameter so i want to know how we can add it by relation or else.

and secondly if i give my mathcad output value in string format then i am not able to make its integration.

Thanks,
