Hey Ashford,

I was also stuck on this problem last night and figured it out after giving it a break and coming back this morning. Looking at your code, you need to read in a char paramater so the code will know which tile to look for. Also, you need to create an if statement inside your For Loop in order for it to check if the char you read in as a paramater matches the char of the tile and then if it does, increment your count variable. As of now, your code is incrementing your count variable for every tile no matter the char on it. Other than that, your code looks identical to mine. If you need further assistance let me know and I can publish my answer.

Good luck!
