Funky Error

Hello. Plugin worked awesome but I put bad code in and I get this error when I activate plugin and navigate to any page on website:

Parse error: syntax error, unexpected ‘.’, expecting end of file in /home/bytor/public_html/wp-content/plugins/my-custom-functions/inc/php/functional.php(94) : eval()’d code on line 18

I tried changing the file to STOP and clear cache and Activate plugin and it activates but then when I click to go into plugin settings where I can delete the bad code the error pops up again and I cant access page where code is.

I deleted plugin and reinstalled and same thing happens. I deleted plugin folder via FTP and reinstalled and same thing happens. Any ideas, please? I would like to keep using this great plugin if I can fix it. Thanks!
