Linking app with flow from a submit button

Hi,

I have a submit button on my app which is meant to link to the sharepoint list (which works) and a flow (which doesn't work). The problem I'm getting is I get a error with the runtime stating "invalid number of arguments : Received 3, expected 2"

How do I change this to expect 3! as it works with 2.

code: SubmitForm(Form4); Approvalflow.Run(Form4.LastSubmit.'Line Manager'.Email, User().FullName, Form4.LastSubmit.ID); NewForm(Form4)

Screenshot 2020-02-07 at 1.06.22 PM.png

Please help!

You can add an additional parameter in Flow by selected Ask in PowerApps when you are filling in a field.

More details here:

Thanks for this!

I have made the changes in flow, but when I go back to the power app even after closing and reopening it still has the error invalid number of arguments received 4 expected 2

@AB1

Did the error message change? Your original post said: "invalid number of arguments : Received 3, expected 2" . Not "Recevied 4, expected 2".

The next thing you should try is removing the Flow from PowerApps then re-adding it.

I have got all that sorted and feel like I'm nearly there! But I'm getting this error now (in the screenshot)

Is this because the column in the Sharepoint list I have the ID is Hidden?

Please help!

@AB1

Which parameter is UpdateItem_id? 1, 2, 3 or 4?

Flow is likely complaining due to a type mismatch (example: passing a Text value when Flow was expecting a number). If parameter is what is causing the trouble you could try wrapping it in one of these functions

Value(Form4.LastSubmit.'ID')
Text(Form4.LastSubmit.'ID', "0")

Tried both of them and still no luck. Here is my flow:

This is the current flow I'm using the updateitem_ID is both the same on IF no and if yes

Have I done it completely wrong?

I'm not much of Flow expert but what I would suggest it taking a look at the run history and seeing what action in the Flow went wrong. This is what works for me! If we can't solve it here there's also a Flow forum that might be able to help.

Hi,

This is the thing, There is no run history for the flow it doesn't run due to that error I'm getting on the power app. Any suggestions? would it still be a flow issue if it doesn't get as far as running at all?

Thanks for your help so far! really appreciate it!

Hi @AB1 ,

Do you want to use three parameters when calling your flow, while your flow only needs two parameters?

If so, that should be a flow issue.

The parameters that you need when you calling the flow is set in your flow.

Please modify your flow. This issue is regardless of powerapps.

So please post your flow configurations in details in flow forum:

https://powerusers.microsoft.com/t5/Microsoft-Power-Automate/ct-p/MPACommunity

The engineers there will give you some advice about how to modifying your flow.

Best regards,
