Scenario - I have a simple logic question with branching in my MS Forms form. The Donation Amount is not required and because of branching, it can be completely skipped over and left blank:

Would you like to donate?

If Yes, branching leads user to filling out their donation amount.

If No, branching leads user to clicking the final submit button. So, the value could be null.

Power Automate uses a workflow and populates the field data into a SharePoint list. Both the MS forms field and SharePoint list item/column are integer/number fields.

I want the "No" or null branching to populate a zero value into the SharePoint field. I've achieved this through using different expressions, however, each time I input an actual donation amount into the field, my return value in SharePoint still populates zero. I'm not able to figure out how to get my return value to populate an actual donation amount if I choose to input one and not just zero.

Here are the expressions I've used that gets me halfway there:

1. @if(empty(item()?['DonationAmount']), 0, item()?['DonationAmount'])

2. if(empty(item()?['DonationAmount']), 0, float(item()?['DonationAmount']))

Any suggestions?

Thanks!

Building flows

@KB-27111647-0 It's hard to offer any recommendations without seeing your full flow and the logic behind it. If you are using the new designer, toggle it off and click each action to expand it. Upload a screenshot of your flow in edit mode.
