Business Language for "Good looking out"

I am looking for a business language alternative to the slang "good looking out" meaning something similar to "thanks for looking out for me" but with a more familiar tone appropriate for use with a colleague. Some versions I’ve kicked around:

• "Thanks for looking out for me" – Too formal, seems like this person is a guardian or overseer to my work and not really appropriate for a colleague.
• "Good catch, thanks" – It’s not really a catch, so much as them giving advance notice of something that could be an issue. They’re catching an issue sure, but it’s not so much a "catch" as much as it is a warning of possibility.
• Simply, "thanks" – I’d like my coworkers to be a bit more open with me than just a "thanks" to end the conversation. I’d like it to be a collaborative effort to keep the team going, so a droll "thanks" does’t seem to do the trick.

What is a good business alternative for the slang, "good looking out"?
