Parse error: syntax error

Hello –

I am new to .php and was looking at the main index template (index.php). I clearly did something wrong because now I am getting the following message when I try to go to my website:

Parse error: syntax error, unexpected ‘{‘ in /home2/rainmake/public_html/Theatre4/wp-content/themes/atahualpa332/index.php on line 148.

1. How do I count the lines to find line 148?
2. And can I then post the code for help to find the error?

Thank you!
