Dealing with Enviroment values of BuildForge

Hi,

I have defined a Project and defined Environment in Pulldown options
Adapter_Name= SAPAdapter,EmailAdapter,etc

Project is defined with several steps , and 1 of the step need different value for Adapter_Name, like sap, email etc, so I have created ENV variable and have assigned Adapter_Name=sap,email etc

But while executing the project, defined step is not able to take the respective values dynamically instead its taking default value which is defined at the top

Please help me in assigning the Environment values dynamically. I have attached some file for your reference.
