Hello,
I have a flow where I have split the text from the body of an email, and for the most part it is successful. My issue is that for certain output of those variables, it includes text I do not want in the output. For example, my weight variable will comeback as "250 lbs" where as I need it to come back at "250". Another word I have to delete is "inches". Can anyone help me with this? I have attached a ss of my flow for reference.
@macdonal_T You will need to use the replace() function. The replace() function takes three parameters:
replace([text string], [old text], [new text])
In the demo below, I'm using a Compose action to store a string.
Add another Compose action. Insert an expression and the replace() function.
For the first parameter, click on the dynamic content tab and insert the dynamic content that contains your string. In my case it's the Compose action.
Add a comma, and in between single quotes enter the old text. In your case, it's lbs. Add another comma and single quotes.
Run a test. Review the outputs. Tip: To get rid of the extra spaces add a space before and after the lbs text.
Wrap the existing expression in another replace() function. Not sure what it means to wrap a function? Check out this section of my tutorial:

In this section, I'll cover how to get dynamic content with an expression when the dynamic content you need isn't listed in the dynamic content menu.
In the full tutorial I cover 7 functions you need to know when getting started with expressions.
1️⃣ empty()
2️⃣ coalesce()
3️⃣ equals()
4️⃣ if()
5️⃣ concat()
6️⃣ length()
7️⃣ split()
I cover how to use these functions in expressions and I’ll also cover common mistakes when it comes to writing expressions and show you a few tips and tricks along the way.
As a beginner or even an intermediate flow builder—expressions can seem a bit complex at first, I’m going to try to simplify it for you. If you want to level up your flows by writing expressions—keep watching!
