im trying to create a private modpack between me and my friends, i installed about 30+ mods into my mods folder in the .minecraft file but when i tried running the game it didnt open.

*I will also need help on creating a server for this private modpack.

This is my "Crash Report" i think...

from what ive seen this usually happens when youre trying to load a mod pack and you either have the wrong forge loaded so its throwing an error saying forge is bad so you need to get the right one for your mods. OR your modpack although is shared doesnt have this file modpack.pack? i think it was. probably not though but its a file that tells your game what order how to open and handle the modpack in question. you cant just drop a modpack into your game and watch it do its thing. it needs a file thats gives it a load order

let me say the steps i took to "install" the mods.

so my friends and I got a short list of mods we liked.

after that list, i went on the internet to download the mods, i made sure all of them were in the minecraft game version of 1.7.10.

after i had downloaded all the mods, i installed the forge through the forge installer minecraft version 1.7.10, i ran the game so that forge intalled correctly, and after that step i placed all the mods i had downloaded into the mods folder in the .minecraft file, and ran the minecraft game. then opened minecraft again and got that "crash report"

its a private modpack best i can give is advice. check out other peoples compiled modpacks see what files they use what they get when the modpack load perfect example would be tekkit. you cant just drop a tekkit pack into a regular minecraft launcher and expect it to work even if you have forge and all that set up there is an accompanied modpack.txt or something file to go with it, once you get that file though it works ive done that myself. also if youre doing a modpack and getting problems like this while trying to share it all in one as a pack try and see what happens if you install it the hard way then if you get errors put it here. go grab the correct version of forge get the correct versions of your mods none of them can be outdated or updated too far ahead download them one by one and throw them in the mods folder like they are supposed to be and see what happens its pretty much touch and go.
