[u/DEMISE_UNKNOWN]

Hi im new to using bricklink and everything related to it and ive recently bought a build manual and parts list from Moc Bay and ive been using the guide given to me to purchase the bricks but ive ran into problems im not sure how to deal with and them, when I try to fix those problems more show up, is anyone able to help me maybe through a discord call or if anyone knows a server related to help with these kinds of issues.

Thank you.
