Invalid Argument Type

Posted on by arseyam

Hi,
Please I need support with my problem

I'm trying to update the default value for a Data Card with the formula below but I'm getting an invalid argument type

'Compare List Gallery'.Selected.ManufacturerName & " - " & 'Compare List Gallery'.Selected.'Device Name'

If I used 'Compare List Gallery'.Selected.ManufacturerName or 'Compare List Gallery'.Selected.'Device Name' as a value alone it works fine so I expect that there's something wrong with the formula itself.

Please note I copied the formula from Microsoft PowerApps in a Day training material so it should be working fine.

Hi @arseyam ,

What type of field are you writing back to? If it is Text, this should be valid on the Update of a Data Card referencing that field.

Yes it is a text field but I don't know why I'm getting an error.

Hi @arseyam ,

Put the same code in a label and see if you get the expected result displayed.

Hi @arseyam ,

Something strange here - I actually have the same list here (from an MS workshop) - label Text as below

Your code is correct provided your references are also.

Hi @arseyam ,

It is possible this is another result of this current known bug on the latest authoring version (although I have not seen this one before), but you could set a Variable on the OnSelect of the Gallery and use that to update.

Hi Warren,
I haven't tried the variable, I just started another lab and gave up on this one 😅
