A few things here:
Your href attribute is missing. It appears to simply have an opening " with no string or closing ". You didn’t complete your opening a tag. Remember that quotes (" or ') must always come in pairs and every opening bracket (<, { or [) must have a corresponding closing bracket (>, } or ]).
To add to the great guidance of @ArielLeslie , I would like to mention that it may be best to reset the step ( this will not affect any of the previously completed steps) to have a fresh code for this step.
Do not add any additional attributes to the anchor, except what the step requires. (I noticed an unmentioned attribute added to the anchor.
@ArielLeslie has provided you with the guidance to the solution for the problem with he code.
