What is the correct Regular Expression for preventing a space in a variable?

[Zhane]

I am trying to prevent any spaces on a variable and set up a regex for this and it's not working

Hi Zhane,

I would recommend changing your regex to ^\S+$

Have you added the regex to the variable itself? (Note:It will only work on particular variable types)

There is a field on the variable that needs to be set to your new regex record - Validation regex (you may need to add this to the form layout)

I created the updated regex (^\S+$) in my own instance and it works after I added it to a single line text variable

Hope this helps,

Shane

Can you try with the below regex?

Regex - ^\S*$
