Tell us what’s happening:

It says i should have a print statement. but it is there and i see no syntax error

Your code so far

The way that you are trying to get the key:value pair from the invalid_records variable is incorrect.

There is a resource you can use to refresh on how to access dictionary items. this is why your code won’t pass because you are not finding the invalid entries. If you still have trouble reply to me and I will try and assist further! Good Luck, and Happy Coding!

Welcome to the forum @andrew.paolinetti!

You are just missing punctuation at the end of the message. Your code is fine.

I tried, Thanks @dhess for correcting my mistake. I don’t mean to mislead anyone. I was thinking that because val wasn’t defined anywhere else that a syntax error was probably showing up in the terminal. Those punctuation get me every time also though @andrew.paolinetti gotta watch them like a hawk. I assume though that becuse val is defined further down the block that no error populates. In my head i thought it needed to be before the point where the variable was defined.

duh. massive brain fart on my end. You make the variable name essentially whatever its what the variable points to that matters. IDK what i was thinking. sorry if i miseld you @andrew.paolinetti
