BSM 9.03 - How to change the script parameters on a BPM

Hello everyone,


I've been trying to change the script parameters for a BPM that I created on BSM-Admin-End User Management.

I cannot add or remove values for the existing script parameters since the field is greyed out.


The solution I've been implementing so far is to download the script everytime I want to make changes, edit the necessary parameters using VuGen and then re-upload it to BSM-EUM which takes quite some time. 


Please have a look at the screen shot for a better idea of what I'm talking about.
