I need to add an item value from one SharePoint Online list to another but can't figure out how to do this since I'm unfamiliar with Expressions and have not been able to hunt down an example.
I want to Add List B number to List A number. I'm assuming I have to use the expression add(Sumand_1:number, Sumand_2:number) in the List A field. Is this correct? If so what does it look like? Is it add(Sumand_1:List A number, Sumand_2:List B number)?
Also is there a site that provides examples of expressions?
Is this the doc you are looking for?
There's a basic example provided.
I'm trying to do a Flow that mimics a Sharepoint Designer workflow. In Sharepoint Designer, you would set a variable to the value of the item in list B and then add that variable to value on the item in List A. Pretty simple once you set your conditions up. The reason I'm not using a Workflow is because it is has not work consistently with SharePoint on line. So I wanted to give it a try with a Flow.
The lack of documentation surronding parts of Flow is surprising. Expressions is a good example. "Power Users" are not going to use this capability when the documentation is geared towards Azure.
Joe - Flow for sure has a ways to go in terms of stability and documentation. Sorry the link didn't help. Best of luck to you - maybe someone else has some ideas?
@Black7830- Here is an example that may help you.
I have a SharePoint list with a number column. When an item in the list is created or changed, my Flow runs.
I initialize a variable and set it to the value stored in a column called NumberCol and add 10 using the Add expression.
In your case, you'll need to retrieve a row from List 2 and reference the value of a second number column in the expression. You will likely be put into a loop but this shouln't be an issue as you should only be retrieving one row.
I then update a SharePoint columns by setting it equal to the variable.
If this does not work for you, please provide additional details and I will enhance my example.
If this does solve your issue, please mark your post as solved.
Hi Scott: Appreciate the assistance. But where does Initialize Variable come from? It is not a SharePoint Flow Action, Trigger or Expression.
Have you had an opportunity to apply @jannaj‘s recommendation to adapt your Flow? If yes, and you find that solution to be satisfactory, please go ahead and click “Accept as Solution” so that this thread will be marked for other users to easily identify!

did you get this working? I'm doing simple action compose with add expression and cant get syntax right. I get item to pickup a number and simply want to add 1 to it. Have tried several things add([credit # sequential],1) and add('credit # sequential,1). Nothing works.
When you say it doesn't work, does it generate an error? If so, what error?
Also, a screen shot of your expression would be very helpful.
My flow starts when 'credit request' entered. I then get item 'credit number' sharepoint list which just had the last number in a doc. I then want to add to that field and update it in the credit number list and the credit request. My issue is the add function. I've tried add('Credit # increment',1) and says its a string. I've tried add([credit # increment],1) and it says invalid syntax. Tried below syntax also. I just cant seem to get syntax right for the add expression. thanks in advance
Try converting the Credit # to a number before adding anything to it by using either the int() or float() expression.
