I need help for finding my mistakes


//this is some code that i work but it doesn't seem to work. i would be very grateful if you could help me

var perimeterBox = function(length, width)
return(length + length + width + width);



on your function call:


you separate the arguments with a semi-colon, this should be a comma, from the instructions:
To call a function with more than one parameter, just enter a value for each parameter in the parentheses. For example, areaBox(3,9); would return the area of a box with a length of 3 and a width of 9


thanks you so so much
