Using remix

I continue to get a \* declarationerror : identifier not found or no unique  
---\> contracts/Token.sol:7:5:  
|  
7 | uint256 public approveddecimals = 18;  
| ^^^^^^^

for my line of code here : unit256 public decimals = 18;

I'm very confused and stuck when trying to compile

Try  
Uint approvedecimals = 18;

Remove the public this a state variable

And also depends on how you use this variable in the smart contract that created the error
