Hello,
POST UPDATED
I have managed to sort out the issue below. I deleted the flow from power automate and the power apps and reinstated them. The number of arguments are now correct (41). The issue that I am now having is that there are "invalid arguments". The purple elements work wonderfully, the other... not so much lol.
SubmitForm(Form1);If(IsEmpty(Errors('MySuccess@Work')),Notify("Success",NotificationType.Success);Navigate(MainAppScreen),Notify(First(Errors('MySuccess@Work')).Message,NotificationType.Error)); 'PowerApp->PopulateaMicrosoftWordtemplate'.Run(DataCardValue23.Text,DataCardValue18.Text,DataCardValue3.SelectedItems,DataCardValue4.SelectedItems,DataCardValue6.SelectedDate,DataCardValue14.Text,DataCardValue36.Text,DataCardValue26.Text,DataCardValue33.Text,DataCardValue41.SelectedDate,DataCardValue22.SelectedDate,DataCardValue35.Text,DataCardValue19.Text,DataCardValue4.SelectedItems,DataCardValue8.Text,Radio1.Selected,DataCardValue16.Text,DataCardValue36.Text,DataCardValue13.SelectedItems,DataCardValue4.SelectedItems,DataCardValue37.Text,DataCardValue28.SelectedDate,DataCardValue5.Text,DataCardValue2.Text,DataCardValue7.Text,DataCardValue27.Text,DataCardValue1.SelectedItems,DataCardValue11.Text,DataCardValue12.Text,DataCardValue38.Text,DataCardValue9.SelectedItems,DataCardValue32.Text,DataCardValue34.Text,DataCardValue15.Text,DataCardValue39.Text,DataCardValue6.SelectedDate,DataCardValue41.SelectedDate,DataCardValue36.Text,DataCardValue21.SelectedDate,DataCardValue17.Text,DataCardValue20.Text)
Can anyone tell me what I am doing wrong? Is there anything special I need to do for DataCardValue?
TIA 🙂
BEFORE FIXED
Have the data auto populate a Microsoft Word Template through ".Run( )". My issue is, is that I am missing an argument in power apps (stating there is only 41 and I need 42). I have had the screens next to each other and copied verbatim. The anomaly I can see in the 'PowerApps Code View', is the following highlighted:

Flow below

Having a look at the Ask Power Apps there is one that is _File but I have no idea what I am meant to input into my Power Apps. Is it referring to the actual file name? If so, what do I input into my Power apps? Do I need to put "PopulateMicrosoftWorkTemplate_File" in the File component of the flow? I even tested the flow manually and it doesn't come up anywhere in the MS docx.
Any help would be greatly appreciated!
TIA 🙂
