Parameter errors in parametric study

[DrBwts]

I'm using the parametric study scripting interface.

I was planning to do a simple parametric study on the Young's modulus & the Possion' ratio of a model just to get the hang of it all.

But it seems that this is not allowed, I get the following errors...

***ERROR: Parameter 'young' is not an independent parameter in 'bone'

***ERROR: Parameter 'poisson' is not an independent parameter in 'bone'

In the *inp file I have...

** MATERIALS
**
*Material, name=bone
*Elastic
<young>, <poisson>

So is this kind of thing not allowed? I would have thought it was a simple matter of text substitution?

To confound me further if I use the following code (ie just with the 'young' parameter)

boneMat = ParStudy(par='young', name='bone')
boneMat.define(CONTINUOUS, par='young', domain=(15100., 22100.))
boneMat.sample(INTERVAL, par='young', interval=3500.)
boneMat.combine(MESH)
boneMat.generate(template='bone')

I get the following error...

***ERROR: Parameter 'young' is not an independent par

***ERROR: The parameter(s) chosen are not independent

Have you specified *Parameter in the input deck?
