Problem renaming model parameters

[brad.bylls]

I am trying to rename and reset values of model parameters.

Everything I find in the forums and help files say this should work, but no luck.

Here is the code I am using:

        product = app.activeProduct

        param = product.rootComponent.modelParameters.itemByName('d1')  << This line seems ok, no error

        param.value = BodyLength  <<  This line throws the error below

        param.name = 'Screw_Length'  << I reversed these two and this one also throws the error

Looks like the screen shot of the error was removed.

It said:

Attribute Error: 'None Type' object has no attribute 'value'

Brad,

itemByName will return None if there is no item with that name in the collection. It will not raise an exception in this case (because it isn't really an error, the search was successful just with no result found). So you should check the returned parameter is not None to determine if the search found any match.

Thanks Kris.
I'll try to figure out where in the code it needs to go.
