"Use the JavaScript .toUpperCase( ) string method to assign an all uppercase version of the id variable to the userName"

I can't get past this assignment. I try doing this:

var id ="23188xtr"; var lastName ="Smith"; var userName=id.toUpperCase()+lastName

But all I get this error message: The userName variable is "23188XTRSmith" not "23188XTR#SMITH".

So, question is: 1: Why does my code turn it into all caps? 2: Why does my code add "#" between the vars?

Hello Andre, you're on the right track. All you need to do is to turn everything into uppercase and add the hash (#) symbol between id and lastname. So something like:

id.toUpperCase + add hash sign + lastName.toUpperCase

Thanks Cheo! However, I'm a bit confused. The task explicitly states for me to add an upper case version of the variable "id" to the variable userName - doesn't that imply that the result should be 23188TRSmith?

And, secondly - what does the "#" do? I watched the "lesson", but it doesn't mention the use of #.

i think there is a logic error here and AndrE is right, there is no need to add the hashtag in task1, but u need to add a hashtag to pass the task. because in task 2, the same task appears and ask to add a hashtag again which was already done in task1.

You want to make uppercase id so

"23188xtr"

becomes

"23188XTR"

Then you want to add the hash symbol (as a string), so

"23188XTR" + "#"

And finally you want to add the uppercase version of lastName, so

"Smith"

becomes

"SMITH"

Putting it all together, you get

"23188XTR" + "#" + "SMITH"

or simply

"23188XTR#SMITH"
