Problem with pasting the link to peer review?

Few students brought to my attention that pasting a link in the comment box does not work. I revised the directions on how to communicate the link to the peer reviewed version of the paper to the person whose paper you peer reviewed. The directions are included here in red, and I also corrected them in the assignment.

Step #5: Peer Review First Draft of Photo Analysis Paper
-Before Wednesday, March 30 class, you and your assigned peer reviewer must complete a peer review of each other’s papers. In order to do so, you’ll access your peer reviewer’s paper by clicking on the link to the peer reviewer’s first draft, which he/she will post on his/her blog by 11:59 a.m. on Friday, March 25.
-Clicking the link will take you to peer reviewer’s paper in Google Docs. Click on File, and then in the drop down menu, click on Make a Copy. A box will pop up asking if you want to make a new copy of the document, click OK. Now in the copy of your peer reviewer’s draft, you will make comments by clicking on Insert, and then on Comment in the drop down menu. When you finish, click on File, and then on Rename in the drop down menu. Rename the document Peer Reviewer’s Comments On Photo Analysis Paper, and then click OK. Then click on Share, in the top right hand corner. Then click on Sharing Settings. In the box that opens, under Permissions, next to Private, click on Change. Then select Anyone with a link, and lastly click Save. Next a box will open with the link, and on the bottom there will be a space to enter the e-mail of the person with whom you want to share the link. Copy and paste the link of the person whose paper your peer reviewed. Below that an option is checked which says an e-mail with the link will be sent to the person whose e-mail you entered. You may also click on the option to Send a copy to yourself.
-As you read and peer review your classmate’s paper, comment on the following:
A.) Is the introduction clear and appropriate for the assignment? Is it engaging? Does it have a thesis?
B.) For each body paragraph, comment on whether or not the writer focuses on ONE aspect of the photo. Also, provide feedback regarding how effective is the analysis of each aspect.
C.) Is the conclusion, which should not introduce any new observations about the photo nor a repeat what was stated in the introduction, satisfying?
D.) What is the paper’s biggest strength?
E.) In your professional opinion, what do you think the writer should improve/add/change in the final draft?
*I’ll also read everyone’s first draft and provide feedback/comments.
