Hi All, 
 I need to show one validation that - throw error if they enter anything apart from 0 to 9 and . 
 How can we achieve that using some functions in appian 
 Can Someone suggest for this?

It really kinda depends on what valid input(s) you're trying to accept. If you're after only decimal values, you could wrap your save in "todecimal()" at save time, forcing any extraneous characters to go away. If something like "10.2.3.6.8.9" would be acceptable though, you'd need to check the text manually - a regex would work, but also you could just use built-in functions like "cleanWith()" i.e. validations: { if(ri!text <> cleanWith(ri!text, "0123456789."), "Invalid Characters Entered", null()) }

sid said: what if user provides 8..9.7 
 all you said originally was "0 and 9 and ." That doesn't exclude having 2 periods in a row. If two periods in a row is not allowed, obviously your algorithm for validation will need to be a bit more complex.

Use regexmatch(). It will be useful to achieve your requirement.
