**Your software**  
My Mautic version is:3.3.2  
My PHP version is:7.3  
My Database type and version is: Mysql

My problem is: When a user registers from a specific form I want to have Mautic begin specific campaign…Is there anything that can be placed in a hidden field to let Mautic know that I want this to happen immediately upon a user logging in from this particualar form?

These errors are showing in the log: None

Steps I have tried to fix the problem: Looked tons of previous problems to see if i could find anyone having this particular question… with no results.  
Any suggestions would be greatly appreciated.

Hi tommytx123,

> When a user registers from a specific form I want to have Mautic begin specific campaign

This should be simple, no need for a hidden field:

- The straight-forward way would be to use a campaign form, and let that be the starting point for your campaign.
- The other option would be to have a standalone form, and add a “Modify contact’s segments” action to it. Plus have that segment serve as the campaign starting point.

Best,  
Ekke
