Workflow Automation Instant Action

Workflow Automation Instant Action

Hello All

I need help to resolve this.

I have created a few workflow

1. When Deal Stage is Submitted to Onboarding, it will create a record in my Onboarding Module
2. When Deal Stage is Live, It will copy $Deal.GOliveDate to $Onboarding.GoLiveDate

For the first workflow it work, however when i use the create action for the 2nd workflow it will create a duplicate.

I also try to use the update action however it doesn't update

I have create to create a custom function but it doesn't update.

Can someone tell me how should i go about this?
