I have created an ERC20 token, but how does it get value?
Right now, 100,000,000 BST tokens are worth 0 Ether.
Can someone help me learn how to get the tokens to gain value?
ERC20 tokens do not have any inherent value. If you want to bring value to the token, you must make it something desirable by others. This could be through a utility that the token provides access to, or a security that the token represents, or even building a community that has an irrational love for the token.
If you want the token to have value, people will need to want to buy it, and that is not something you can pull out from thin air.
