PHP Parse error: syntax error, unexpected 'else' (T_ELSE) in ... on line 179 [duplicate]

My first question in this forum. If I haven't supplied enough info, please let me know.

I am receiving an error in a PHP if/else statement and the page does not load - page error is HTTP error 500. I'm not very experienced in PHP, but what I have written looks ok to me. Apparently it is not. Seeing if anyone can point me to my error.
