Hi all,


I've a question about how to select a specific value to a variable.

I've a SharePoint list with multiple identical values. I need to add the value to a variable to use it later in my flow.


I use this part of the flow where I try to set a single value, for example 10009 to my variable. 


How can I filter only the value I need and drop that in to my variable?


I guess it will result in an apply for each because there are multiple hits in my list for some titles. But how can I get only the number into the variable? (I need to set the number as odata query in a get items action)


Thanks in advance

I misunderstood what you are trying to do. Am I right in saying that you just want an array of values, like:

[ "10009", "1049" ]

if so, try this instead:

Hi @Paulie78 ,


Thank you for your reply.

I'm trying to get the results, but I've a question about this part:



What do I add in the right expression? When I try 

string(['RelatieNR']) I get an error:  "The expression is invalid".
Thanks in advance

Where 10009 is the id of the one you want append to your array.



You can use Power Automate expressions to filter the information as required.

As the information is coming out as an array you can use expressions to get the desired item in the variable.


Let us say that I have to select the first item coming out then I can use the below expression

The same way if you have to select the 4/5 value then you can replace the 0 with 3/4 as the array index in flow starts with 0.
If the information shared helps you, please give a thumbs up 👍 and mark solution as resolved.

Hi @Paulie78 ,


Thank you for your reply.

Sorry but I'm not really know how to fix that. The number 10009 is not a static value.

From what action item can I add to the string value?


I've tried this, but that's not working:


If possible, can you tell me what I need to enter to get it work?

Hi @Paulie78 ,


Thank you, that's the solution.

A little thing I need to do is now to remove the [""] 


I only need the number itself, if have, I'm finished 🙂




You don't really want to do that, the brackets represent an array, which means you could do an apply each on them to run a get items on each element of the array. It sounds as though you have ended up with only one value in the array so you could get rid of the array formatting by doing:


It's hard to guide you exactly because it is not completely clear what you are trying to achieve.

If you are going to loop around each of the items in the array then you can just use:


 and that will have only the value of the item and not [ "blah" ]

Hi @Paulie78 ,


Thank you.

For your information, What I'm try to do, I've described it in this topic.

I need to get all the list items, and send an e-mail to an e-mail address thats in a column. Only, for some customers in the list, there are multiple items in the list, I don't want to send them multiple e-mails but bundle the information in a html table and send it to the customer. The unique value for every customer is the relationID to match all the items for a customer.


So I was try to get all the list items thats belong to the same relation ID. With that information, I need to put it in to the html table and send it to the customer by email.


I'm hoping I'm on the good way to do that with above steps.

ok, I got you now. So with the array generated in the steps already created you can easily create a HTML table from that (you might have to manually specify the column names if using the array of just values). 

But equally you could use the array of properties and values in the compose action to do the same (and it would automatically generate the column names). Either will work.
