Unable to submit form when number field exceeds 19 characters

(0) ShareShare
ReportReport
Posted on by Tricky778 90

We have a Text Input number field on a form, linking back to a SharePoint list. When I enter 20 characters:

 

86700202700015502976

 

Select to submit the form, it fails with the following error:

If I then delete the '6' at the end of the number string (so that we have 19 characters) it will submit fine. 

The field has no maximum length set (in both the PowerApp or SharePoint). Have tried the following:

 

  • Setting the maximum length to 30 in the PowerApp
  • Deleting the field in the PowerApp and pulling it through again to the form
  • Tried another number field on the same form, failed with the same error

Is there a default 19 character max I'm missing somewhere? 

 

Thanks

    Its not a 19 character max, but the text box is automatically recognizing the entry as a number and there is a 19 digit limit on numbers.  If you enter a character in the box you will find that it recognizes the number as a string and won't truncate the number until you try to use it as a value.

    Thanks @Pstork1 ,

    Is there any way around this for instances where you're anticipating more than 19 consecutive numbers to be input into the field?

    No workaround that I know of other than forcing the text box to consider the entry as text rather than a number.  That requires input of some kind of alpha character.

    Okay thanks for confirming the behaviour. I'll edit the field so it asks for the country prefix as well as the number. Thanks again
