Go to this page and find which of the three Muncie-area repeaters you are trying to connect to: https://mygmrs.com/map/. Then we can give you some numbers.
EDIT. Check that. Two of those are paid membership, which you can look at later if you wish. For now I suggest you connect to WRAM564, which is an open system. You'll need to transmit on 467.650. This is channel 27 labelled "RPT - 5". Go there, call up the menu and set a transmit tone of 118.8. Listen with no tone.
This repeater's specs are here: https://mygmrs.com/repeater/9044. Even though the repeater is labeled "Open", it's always polite to request access, either by clicking the tab in the upper right or asking verbally.
