In SharePoint Online, I have created a simple power app on a custom List. I want to add a validation on Title Column (Start with "Project -") on Form Submission. That is, user should not be able to submit the Form if Title column value doesn't start with "Project -". User should see an error and then they should modify the Title value and save again.
I found Validate function in PowerApps link but unable to understand how to apply this to the form for my custom validation.
Please let me know how to add custom validations on list fields in Power App Form?
Thanks in advance
