Error with expression in condition

[abwaters]

I am trying to use the addDays expression to check if the current date plus a number of days saved in a SPO list item equals the Due Date saved in the same list. I do a Get Items > Current Time (for today's date) > Filter Array to only use items with a status of "In Process" > then an Apply to Each containing a condition with the following:

@equals(addDays(body('Current_time'), int(body('Get items')?['First warning'])), items('Apply_to_each')?['Due_x0020_date'])

My second parameter always returns null. I have tried changing "body('Get items')?['First warning'])" to "items('Apply_to_each')?['First warning']" but still get an error. 

Please help!

Hi @abwaters,

What is the type of the "First warning" column in your sharepoint list?Is it s Number type?

I have made a test on my side to create the "First warning" column in sharepoint list with a Number type, and I have create the flow as below:

The expression in the Filter array as below:

@equals(item()?['status']?['Value'], 'In Process')

The expression in the Condition as below:

@equals(formatDateTime(addDays(utcNow(), int(item()?['First_x0020_warning'])), 'yyyy-MM-dd'), formatDateTime(item()?['Due_x0020_Date'], 'yyyy-MM-dd'))

The flow would run successfully as below:

Best regards,

Alice

Yes the First Warning field is a number type - number of days before the Due Date. What you put up is very helpful. I really appreciate it. I think the expressions are pretty powerful if you understand the syntax. I actually have my flow working great. Just have to get the data in my SPO list. 

Thanks again!
