OpenSP: ID ... already defined
An "id" is a unique identifier. Each time this attribute is used in a document it must have a different value. If you are using this attribute as a hook for style sheets it may be more appropriate to use classes (which group elements) than id (which are used to identify exactly one element).
|<span id="name1"> <span id="name1">|
|<span id="name1"> <span id="name2">|
Use an unique ID or a class name.
