How do I limit which user can see certain elements of the Sharepoint list custom form?

[KarlXII]

Hey, I'm working on a little project where me and my boss want to enable the employees, to submit their projects automatically via a list of projects in Sharepoint. Each project is assigned a "Responsible person" and we want him to be able to submit the finished product via customized list form and we want only the Responsible person to be able to see the attachments window. I've created the flow CheckAuthority in PowerAutomate, to verify that the user is in fact listed as the Responsible person which is below:

It asks in PowerApps for the email of the current user and for the Index of the item in the list, so that it can then compare emails of the current user and the user, that is listed as responsible person for this specific project. I call this flow with <Set(Value, CheckAuthority.Run(User().Email, DataCardValue9.Text))> in the <On visible> property of the FormScreen and with <If(IsBlank(Value) = false, true, false)> in the <Visible> property of the Attachments window.

I keep getting the error "The method 'Run' has an invallid value for parameter 'Getitem_Id'". I have no idea what goes wrong and why this report message.

CheckAuthority.Run(User().Email, Value( DataCardValue9.Text))

assuming DataCardValue9.Text is SharePoint ID 

and also you dont need to use Flow for your requirement you can achieve the expectations with powerapp itself

I tried this, it didn't work. I'll look into getting this to work without a loop.

I agree with DeveloperAJ that you should be able to achieve this same thing within PowerApps itself and it will likely function a lot better. From my experience running flows like this add a lot of overhead and unnecessary wait times for things to process. I would have to have a clearer understanding of the application and your requirements to give more concrete advice, but I would suggest looking at adding more controls on the PA side.

[developerAJ]

are you still receiving the error

[KarlXII]

Yes

[developerAJ]

CheckAuthority.Run(Value( DataCardValue9.Text),User().Email)
