Hello All,
Thanks for taking time to look over my post. I am having issues with my flow and I think I need a push in the right direction.
As shown in the image below, I have it set for when a response is submitted to create a case. This will be used for a inter company support system. So people within the company will go to this form and submit their response. When that happens I want a case created in CRM with their information listed.

I have it so all cases are tied to a specific account in CRM. I found that I needed to use the ID for the account to make it work. What my trouble is, is that the flow needs a contactID to create the case. Shown in the image below you can see the accountID and the contactID for my test user. I found that I needed to have the ID's in these fields after getting syntax errors repeatedly when using the dynamics fields that were from the form 'EX 'responders email'.

Where I am stuck is that these responses will be done many the members of the company. There is no way for me to grab their contactID's. The only reason that I was able to my example to work is because I have the ID for my test user in there. I don't know of a way to have that auto populate or a way to grab that information. The only place that I am able to see the contactID is from the URL on that contact record in CRM.

I am looking to have this work off of the who ever submits the form. However Power Automate needs the ID to work. Any thoughts or tips for me?
