Submit and Next buttons do not work on Service Portal catalog itemIssue When selecting Submit or Next on a Service Portal catalog item, nothing happens and the item does not submit. The following error appears in the browser JavaScript console: ```Overwriting extension point: g_validation_script_field_count``` This error indicates that a duplicate or conflicting client validation script is overwriting an existing extension point, preventing the Submit and Next buttons from triggering any UI action on the catalog item. A known scripting conflict of this type should be investigated in the catalog client scripts or variable sets associated with the item. One possible cause is that the catalog item contains a duplicate variable with the same internal name.

In this scenario, the duplicate variables for `employee_end_date` prevent the form from submitting. A variable set cannot contain two variables with the same internal name. Resolution 1. Identify the catalog item that is not submitting. 2. Navigate to the catalog item's variable configuration. 3. Review the list of variables on the item and in any associated variable sets. Look for variables that share the same internal name — in this scenario, the duplicate internal name is `employee_end_date`. 4. 5. Remove or rename the duplicate variable so that each internal name is unique within the variable set. 6. Save the changes and test the catalog item in Service Portal by selecting Submit or Next to confirm the error no longer appears.
