How to error check for only numbers from user input in an analytic app

[csh8428]

I have an analytic app. One of the user entered values can only be a positive number(can be a decimal). I know how to error check for blank values, but not how to check for data types.

What expression would I enter into the error tool to check for that?

Thanks for any help!

@csh8428 I would suggest using a Numeric Up Down tool instead of a Text Box tool if you want your users to only input numbers. The configuration allows you to set up/down increments, min, max, and decimal places.

@csh8428 You can use the Regex function to check whether the incoming data is numeric or not

REGEX_CountMatches([#1],'[^\d\.]')>= 1
