Expected a string error in number field



I’m a PowerApps beginner and have been experiencing a specific issue for a couple of months. Here is my original post. I’m still wondering what I’m doing wrong. A prior version of my app became unusable due to the same problem, so started over from scratch with a new data source, and now the problem has returned to haunt me again.


Here’s the situation: I have a data card in the form “RecordEditForm” connected to a number column in my excel data source. The data card contains a text input that is supposed to accept and save only numbers. The following examples are pictured below: A) my save button executed the following command which saves all data cards in RecordEditForm: SubmitForm(RecordEditForm), B) yet, I still receive this “Expected a string” error message when I save. 


Everything was saving properly until about 2 hours ago, after I customized several other data cards in my form.  I receive an error message when I clicked the save button, informing me that the field for my DOM Cost Share data card “expected a string”. I can’t figure out the reason for this expectation. As far as I can tell, everything is set up to expect a number.


A) The column in my Excel data source connected to my field is set to Number.

B) The update property of my data card converts to value.

C) The default property in my text input is Parent.Default

D) Format property of my text input is set to Number


I’m not sure what to try next as I’ve already tried starting from scratch. Unlike the last time, the data type of the column in my data source is not reverting to text or general when I save. It remains set to Number even after I receive the error message. I check by opening my data source after I get the error.


Any ideas on how I can fix this? Should I abandon my forms and create my own text inputs?
