Hello,

@iAm_ManCat

You responded to a user on this topic: https://powerusers.microsoft.com/t5/Building-Power-Apps/Respond-to-a-power-app-or-flow-Variable-help.... I was wondering, if I have a global variable varReturnResponse and I have two variables I can call(successmsg and errormsg), How would I go about using the notification function to display the correct message?

This is the gist of what I have so far. Any help would be greatly appreciated.

Sure,

So it looks like you are already setting this as a variable, varReturnResponse, so you should set the flow run as varReturnResponse then use an if condition separately afterwards

Something like this (replaced your control names with generics, please change all of those to your control names):

Set(varReturnResponse, FlowName.Run( abc.Value, def.Selected.Value, ghi.Selected.Displayname, jkl.Value, If(IsBlank(mno.Value), "", mno.Value), If(IsBlank(pqr.Value), "", pqr.Value), If(IsBlank(stu.Selected.Value), "", stu.Selected.Value), If(IsBlank(vwx.Selected.Value), "", vwx.Selected.Value), User().FullName, User().Email ) ); If(Len(varReturnResponse.successmsg)>0, Notify("" & varReturnResponse.successmsg, NotificationType.Success, 10000), Notify("" & varReturnResponse.errormsg, NotificationType.Error, 10000) )

Cheers,

Sancho

Did you replace the flowname in Flowname.Run( ?

Silly me, that was the issue. Now the messages are displaying correctly. Thank you so much!
However, now I'm noticing the form still submits even though a required field was left blank and the correct error message shows up. Is this something I need to fix on the power automate flow side?
This is the required fields piece I have in flow.

I would say, that you should use some login in the DisplayMode of the button that is running the above code to only be enabled when all required fields are filled - that way you can't press the button or run the flow until all required fields are completed

Thank you! That works. For anyone interested in the code:
If(FormName.Valid,DisplayMode.Edit,DisplayMode.Disabled).

Lastly, for curiosity's sake, I would no longer need a variable for the error message since I went with the "disable submit button" route correct? Would I even need the required fields piece in my flow?

If that's the only possible error then yes - in my experience there are many other ways a flow can error and I would always catch that at the end of the flow and pass it back to the app so that at least the user is aware of what went wrong.

You've been very helpful, thanks so much! I'll take a look at the try, catch method and see how that works.
