Power Automate Expression loses Dynamic Content fields

[Gadgetgeek]

Just getting started in Power Automate and I need some help with Expressions. If you know of a good resource for understanding Expressions I would love to read that.

I've got a simple Power Automate flow I'm trying to create. The flow reads lines from an Excel table with the "List rows present in a table" step. I then added an Apply to each and selected the value from the Excel step.  All good so far.

I then am taking that value and creating a Dataverse table record with the "Create new record" step.  I feed in the Excel table columns by name and everything works great. Except my table column "Join Date", which requires a date-formatted value. The value from Excel is a date serial.

So, I removed the Dynamic content value, and click Expression. Looked for the formatDateTime, which shows when I type, but isn't in the list of functions. ??? Then try to reach back in the Dynamic content to grab the field, but the field has disappeared.  I'm confused. It happens if I choose any expression...the Dynamic content only shows Excel body and value, not the fields.

@Gadgetgeek if you dont see the dynamic content from the list, just hover above the "Join Date" and you will see the equivalent expression for that which you can type inside the formatdatetime()

I see. When I hover I see this:

items('Apply_to_each')?['Join Date']

Good start. Thanks!

"FormatDateTime" didn't work, but this did work. Thanks @krootz 

startOfDay(items('Apply_to_each')?['Join Date'])
