Unspecified error working with oUserParams.AddByValue:

[agsiviglia]

Hi,

I am trying to add a user parameter to my assembly.

(totalArea is a variable that is calculated in another part of the code)

When I run this code, an unspecified error occurs on this line:

Dim Area As UserParameter = oUserParams.AddByValue("Surface Area for Buttering",totalArea,"in , in")

Any tips for dealing with this? I can't understand what I'm doing wrong since the error is unspecified Any help is appreciated.

   oUserParams  = ThisAssembly.Document.ComponentDefinition.Parameters.UserParameters
	
    ' Try to find the existing parameter
    Try
        ' Attempt to retrieve the parameter by name
        Dim r As UserParameter = oUserParams.Item("Surface Area for Buttering")
    Catch
        ' If the parameter doesn't exist, add it
        Dim Area As UserParameter = oUserParams.AddByValue("Surface Area for Buttering",totalArea,"in , in")
    End Try

.

Hi @agsiviglia 

just at a glance I think the issue is the spaces in the parameter name. If you try to create that parameter manually I think you will be greeted by an error message about invalid characters.

also, it looks like the units specifier is included 2x which will likely cause an error too

Thank you!
