I have a field set up for a URL. I want to make sure the user enters 'http://' or 'https://' at the beginning of the URL. If not I want an error message to show, I've tried this but for some reason it only work is only 'http://' or 'https://' is entered. Anything after that it fails. What am I missing?

If(!IsMatch(TXT_BaseURL.Text,"^https?://.+"),Notify("Invalid URL: URL should start with 'https://' or 'http://'",NotificationType.Error))

Another option is to preload the field with "https://" in the value property, or you could just auto-fix it for the user whenever the data has to be submitted. If you were just saving the input to a variable, you could do it like this:

If(
!StartsWith(Lower(txt_url.Value),"https://") And !StartsWith(Lower(txt_url.Value),"http://"),
Set(varUrlInput, $"https://{txt_url.Value}"),
Set(varUrlInput, txt_url.Value)
)

Did you try using MatchOptions.BeginsWith

If(!IsMatch(TXT_BaseURL.Text,"^https?://.+",MatchOptions.BeginsWith),Notify("Invalid URL: URL should start with 'https://' or 'http://'",NotificationType.Error))
