Symptoms

I have a rule that states that when a button is clicked, a new browser window opens, with a given URL with a single parameter. The name of the parameter in the rule is a mix of upper and lowercase letters.
But when I click the button on the form, a new window opens with the correct URL, except that the parameter name is now lowercase only. This causes the page to load incorrectly.

Attached are screenshot of how the URL is defined, what the outcome of the rule, and what the desired result should be.
