Pre-populating Form values to another form.

I am having trouble passing data from one form to another using a URL.

From form https://form.jotform.com/90218665709161 , after putting text in the field under the Wedding Dashboard Title {input87} . . . I have a link set up in the 1st paragraph of copy under the words "Wedding dashboard" that is supposed to open a second form https://form.jotform.com/90256097073156.  

In that 2nd form, I am trying to transfer data from {input87}.  I am using this link "https://form.jotform.com/90256097073156?bridesFirst={input87}"- It's not working.

What am I doing wrong?

I cloned your first form, and I did not find anywhere the link to the second form, where the data is being passed. Try adding this link in the Thank You redirect option: https://form.jotform.com/90256097073156?bridesFirst={input87} 

Test my clone version, it works: https://form.jotform.com/90296087295973
