Client script not executing: expected behavior not occurring on form

Client script is inactive or has incorrect Active checkbox status in the Client Script record. (high likelihood)

Table condition does not match the current form's table, or the View condition does not match the current form view. (high likelihood)

JavaScript syntax error or runtime error in the current script or a higher-ordered script is preventing execution. (high likelihood)

UI Policy or UI Action is conflicting with or overriding the client script behavior. (medium likelihood)

Script applies only to specific user roles or conditions that the current user does not meet. (medium likelihood)

Step 1: Navigate to System Definition > Client Scripts and locate the specific client script that should be executing.

Step 2: Verify the Active checkbox is checked and confirm the Table field matches the form's table where the script should run.

Step 3: Check the Type field matches your expected trigger (onLoad, onChange, onSubmit, onCellEdit) and verify any Field name specified for onChange scripts is correct.

Step 4: Open the browser developer console (F12) and refresh the form to check for JavaScript errors that might prevent script execution.

Step 5: Review the View field to ensure it matches your current form view, or set it to blank to apply to all views.

Step 6: Test the script logic by adding console.log statements or alerts at the beginning of the script function to confirm if the script is being called.

Step 7: Check for conflicting UI Policies at System UI > UI Policies that might be overriding your client script behavior on the same fields.

Step 8: Verify script execution order if multiple client scripts exist for the same trigger by checking the Order field and ensuring dependencies are properly sequenced.
