Trouble finding the problem

SMH Thanks MorganS it was a noob mistake kind of figured Id make a few when I started. I made the correction and it works now.

Please edit your post to include code tags. See the "How to use this forum" post at the top.

You know you have some variables. Like you declared a variable called output and said that it is a float type.

You are using another variable called display but didn't declare it anywhere. The display libraries you #include'd don't do this for you. You might have more than one screen or you want to use a different name. So they let you declare your own.

It keeps telling me that the Display is not defind in this Scope. Can someone help me Debug my program the Display Im using is a Blue Oled .96" with a rtc on a uno r3 board

First, "It" is a pronoun with no referent. We might guess that "It" is the compiler. On the other hand, "It" might be your long-dead grandmother communicating with a ouiji board.

Details matter.

Second, you look pretty dumb with the random capital letters in the middle of sentences. Stop that crap.

It keeps telling me that the Display is not defind in this Scope.

Please post the full error message here

Are you sure that the error is about Display and not display ?

You do not have an object of either name in the program. Have you looked at the examples for the Adafruit library ?
