Help, Game won't load in launcher

[smknight2003]

I've created my own mod pack.  It uploaded just fine, then loaded into the technic launcher fine as well.  However when hit play, it starts loading, gets as far as starting to load the assets and goes back to the launcher.  What am I doing wrong?   http://api.technicpack.net/modpack/surprise-me

Pastebin a crashlog.

I'll download your pack later to see more, but a glance it looks like you are running an old version of forge for 1.7.2, and have a mix of mods that are for 1.6.4, 1.7.2, 1.7.10, and 1.8. What version are you making the modpack for?

Thank you.  My son used to do this stuff but is not busy between work and school.  So I tried to do this on my programly challenged brain

[AetherPirate]

Best bet is to pick 1.7.10 as your base. Download the latest version of Forge for 1.7.10. Get Forge working with no mods. 

Then download the 1.7.10 version of the mods you like from the authors website(s) and read the author's instructions. Add them in, one at a time, and launch forge. It it works, add another, if not, fix the issue. 

Plowman made a great guide for this, I will see if I can find the link.
