I am passing a parameter in a url to another view and during the process it
gets changed. An original parameter example that produces the error
is OQYX/173774//ZYO but gets changed to '/viewLit/OQYX/173774/ZYO/' It
drops the second / between 173774 and ZYO. I assumed this was because it
was treating it as an escape character? So I tried adding an r in the
urls.py file but it did not have any effect. Here is my template code for
the page that generates the hyperlink:
<html>
<head>
<meta charset="UTF-8">

<style>
h1 {

h4 {

}
.field {

}
</style>
