Unexpected initializer before 'float'

I did a search and this was one of the links offered:

The error for which I am searching.

I admit it has been a while since I had done any coding for the Arduino.

But this is an error I am getting which I can't understand.

//  Global variables for humidity and temp.
float Humidity      //  Humidity.
float Temperature_   //  Temperature.

When I try to compile it I get this:

expected initializer before 'float'

And it points to the Temerature_ line.
I added the _ to the name just to be sure I wasn't causing a problem with the name/word I chose.

The link I posted at the top is not exactly like my error.

Could someone help me because google isn't really helping.

missing semicolon at the end of the lines. The line before it (missing the semicolon) is confusing it when it gets to the next line.

Thanks so much.

I should have seen that.

Appreciated.
