Condition for count of character in power automate flow

[GPT2]

Hello,

I have a flow that will run when the character starts with 0.

Is there a way to add a condition that will count the number of characters?

Thus, the flow will run only if the character starts with 0 and count of character is 15 digits.

Thanks for anyone who can help.

@GPT2 If you are evaluating a string of text you can count the characters using an expression and the length() function.

length([insert string of text])

@creativeopinion ,can the length of the character be used as a condition?I would like to add it below.

Also when I try to run the flow below using the condition output starts with 0 I encounter an error

Do you have any suggestion in order to run the flow that when the string starts with 0 and it has 15 character it will proceed to the next step?

I am still exploring power automate and still many things to learn.

Help is highly appreciated.

@GPT2 Could you share a screenshot of your full flow. It's hard to provide any recommendations when I've only seen a portion of the flow.

The length of a string of text can be used in a condition.

@creativeopinion Here,  I would like to send the email once it satisfy the condition (the tel number output start with 0 and the number length of character is 15 digits)

@GPT2 When you enter a number into the condition value field—it's viewed as an integer. To convert it to a string you need to use an expression and the string() function. Enter the value into the string() function. In your case, it's a 0. This expression will convert the integer to a string. 

To count the length of characters in your string of text (Compose action with telephone number) you need to use an expression and the length() function.

Click on the dynamic content and insert the output from the Compose action above. 

Tip: You may want to add a Compose action above the Condition action instead to store the length(). Since the Condition action will not output the length anywhere for you to view. This can help with troubleshooting your flow as you can verify the output of the Compose action. I cover how to do this in the tutorial I linked previously. 

Hope this helps!
