Lesson 1: ParserError: Expected ',' but got 'Number' function Store (unit 256 _favoriteNumber) public {

[LegalTechsis]

Please can anyone help me identify what the error is? and how to fix it? The error is as follows;

from solidity:
contracts/SimpleStorage1.sol:10:23: ParserError: Expected ',' but got 'Number'
function Store (unit 256 _favoriteNumber) public {
^-^

but when i try to do it like the screenshot below; there are no errors; that is; close the parenthesis opened in number 5 at number 9. but after i click on deploy i can only see the button for favorite number but not the store button.

Hello @LegalTechsis
You have two errors:
Is uint no unit
and you have a space between it and the number, the correct form is:
uint256 all together.

Hey @LegalTechsis change uint 256 to uint256 in function store
This is the reason why you getting error as after uint there is some space which means new function argument starts...Hence the error.
Hope it helps.
