After the install of Oracle forms and report How do I get the Forms Builder to run?

Basically I am using VMware as my GUI interface and I went to the file named 'frmbld' and double clicked it and then nothing happens.

After that I tried to get it to run in the terminal but it tells me that the file does not exist. I think the issue with the terminal is that the variable are not set for the environment and it is still using the variables that was set for the database. Not sure how the set up the variable for that environment. I tried using the "export" method to set them but it does work. smh. I really need help with this.
