@lyrec81 Thank you for changing the column names. That will help in the long run even though it wasn't exactly the issue.
I just made an example that is basically the same as your flow. I'm going to provide pictures below and some instructions. You should be able to see how the dynamic content is added as an expression.
Here is an overview of my flow. It is the same as yours.
Overview of Flow Actions
This is the original table data that I used to create items in a SharePoint List.
Original Excel Table Data
This is the SharePoint List after the original items were created.
SharePoint List - Original Items Created
SharePoint List Settings Column Reference
Here is the Create Item action. You can see I had to enter the Excel dynamic content manually as an expression.
Create Item Action - manually insert Excel dynamic content as an expression
Here is the Update Item action. This also required the Excel dynamic content to be entered as an expression.
Update Item Expression - dynamic content entered as expression
Update Item Action - the Excel dynamic content has to be manually added as an expression
Here is my updated Excel table that has made changes to the employee's names and salary.
Excel Source with updated data and new rows to add to the SharePoint List
This is my SharePoint List after the flow was run. You can see everything was updated or created.
SharePoint List After Flow Run - Updated Items and New Items
After the flow has run, go back and look at the Update Item and Create Item actions. The expression that was entered is now correctly showing as dynamic content from Excel.
Create Item Action AFTER the flow has run - the expression now displays as Excel dynamic content
Update Item Action AFTER the flow has run - the expression now correctly displayed as Excel dynamic content
If you look at this example you should be able to have your flow set up correctly with a Currency type SharePoint column.
