+Client Script – Validate Short Description
+Overview
+
+This client script validates the Short Description field before a record is submitted. It ensures that the field:
+
+Does not exceed 100 characters.
+
+Does not contain any special characters (only letters, numbers, and spaces are allowed).
+
+This helps maintain data quality, consistency, and readability in incident records or any other relevant table.
+
+How It Works
+
+On form submission, the script checks the short_description field.
+
+If the description is too long or contains invalid characters, the submission is blocked.
+
+An error message is displayed, and the problematic field can be optionally highlighted.
+
+Configuration
+
+Navigate to System Definition → Client Scripts.
+
+Create a new client script.
+
+Set the following properties:
+
+Table: Incident (or the target table)
+
+Type: onSubmit
+
+Active: Checked
+
+Paste the following script into the Script field.
