richTextItem, safeLink issue

Question

Hi, 
 I have a text field where user is entering website. I am using below line of code to provide a link to the user to navigate to the website. 
 Issue is when user to try to enter link "www.google.com" or " google.com " and when they came to the link and hit it is throwing an error. 
 if( a!isNotNullOrEmpty(ri!site), a!richTextItem( text: ri!site , link: a!safeLink(uri: ri!site ,openLinkIn: "NEW_TAB") ), "" ) 
 
 Any suggestions from anyone.

To simplify the data entry of a fully qualified url, I would simply replace any existing occurrences with an empty string and then normalize it at the end. You should also validate it to make sure it is a valid URL, I would suggest using a regular expression for this. https://community.appian.com/b/appmarket/posts/regular-expression-functions . 
 a!localVariables(
 local!value: "https://google.com",
 concat(
 "https://",
 reduce(
 fn!substitute,
 local!value,
 merge({ "http://", "https://" }, { "", "" })
 )
 )
)

 I don't have many suggestions without first knowing some detail about the error message the user is getting. Why not post the error text and/or a screenshot at least? 
 The two things I can think of in advance: 1) are you doing any sort of verification that the user is typing a valid URL? 2 ) Are you appending "http://" (etc) to the beginning of the URL being supplied, or are you assuming they'll type it?

You will need to verify it one way or another - there are numerous Appian text functions which you could use to do this, depending on how strong the need will be - you could use like(), left() , regexMatch, etc.
