item parameter

[Deviram]

Hi,
I confuse how can I reset it.
Parameter (60) for item 60, is not identified. If anchors or initial values are used the referencing must reflect removal of this parameter.
data recode>> how can I solve it?
Thank you..

if you require specific advice about a model, please upload your data and syntax, or alternatively provide a minimum working example:

For a model to be identified, every response category for each item needs to have at least one valid response. Creating a frequency table for each item will show you how many responses are within each response category.
