''Challenge Not yet complete... here's what's wrong: Could not find a button name 'Google_Info' on a Contact page layout.'' I am getting this error even the functionality is working as given.Find the root cause for this,it's blocking me to get the badge

Hi Jyotsna,

I had the same error - you need to follow the instructions in the Trail under the section "Create a Custom Detail Page Button" (last section before the Challenge), this cleared the error for me.
