#ERROR message when LEFT or extracting text formulas used

[Jesper_Holmstro]

Hi guys, have been sitting with this a couple rounds now and can’t get it right. Im extracting a telephone number from a column in Airtable, but when there is no phone number or the word message I get the famous #ERROR. How can I get Airtable to just show it as blank?
My formula looks like this:
IF({Telefon 1},(LEFT({Telefon 1}, FIND("Message", {Telefon 1}) -1)),BLANK())
Any advice is welcome
Regards
Jesper
