# What to do when TestScript shows error?

Do a standalone script test by following the steps given below:

- Copy the script body in a file.
- Save it as `Test.<ext>` (eg: `Test.pl`, `Test.bat`, `Test.sh` etc.)
- 
  - **To execute from local machine:**
    - In OpManager Server itself
  - **To execute remotely:**
    - In the Remote Machine in the path specified in field "Execution Directory"
- Open Command Prompt, and type the CommandLine Field value and replace the placeholders with proper values.
- Now execute it and get the output.
- If it shows error, the script itself contains errors. Fix the script before trying to use it in OpManager Script Templates again.
