+# Incident Count of Selected Configuration Item with Info Message and Link to its Related Incident 
+
+Displays a message showing the count of open incidents associated with a selected **Configuration Item (CI)** whenever the **Configuration Item** field changes on the Incident form.
+
+- Helps quickly identify whether the selected CI has existing incident by fetching and displaying active incident counts (excluding *Resolved*, *Closed*, and *Canceled* states).  
+- Shows an **info message** with a **clickable link** that opens a filtered list of related incidents for that CI  
+- If more than five incidents are linked, a **warning message** appears suggesting Problem investigation for frequent or repeated CI issues.
+- Uses an **onChange Client Script** on the *Configuration Item* field and a **GlideAjax Script Include** called from the client script to fetch the incident count
