a twilio number over and selected that number, uploaded a csv in the correct format I believe because it doesn't give an error message. I don't know what to do.

Action Required: Make sure you have selected an existing Assistant for your campaign. In the Vapi Dashboard, after uploading your CSV and selecting your Twilio number, go to the "Assistant" step and choose an Assistant from your account—this is required for the Launch Campaign button to become active. If you haven't created an Assistant yet, set one up first, then return to your campaign setup. For more details, see the [Outbound Campaigns Quickstart guide](https://docs.vapi.ai/outbound-campaigns/quickstart).

I forgot to mention that i already clicked on an assistant. I actually tried all of my assistants to make sure it wasn't just one not working.

Next Step: Double-check that your CSV file includes a

number

column (all lowercase) with phone numbers in E.164 format (e.g.,

+14151234567

), and that there are no blank rows or header issues. Tip: Re-upload your CSV and review the recipient list for any errors—this is a common reason the Launch Campaign button stays inactive.
