as EB said, there is an awful lot of plumbing. However, your configs might be too big. I think if it’s > 16 Kb, it won’t exec. Also, some any specific line of script cannot have more than x characters in it, like 235 or so. In fact, your first menu line has 262 characters in it, 309 if you include spaces. Try that and play around with it some.
For what it’s worth, my menu based scripts work fine, but it took a lot of tinkering. I also broke up the equivalents to your long lines into two pieces:
//RTCW Class selection script v7 by Ifurita with input on key variables from lots of people
//Updated for Enemy Territory and, in conjunction with et-spawn-select-v3.cfg, allows for scripted spawn point selection
//README!===============================================================
//This script is set up to use 6 keys (7, 8, 9, 0, -, and =) to control spawnpoint, team, and class selection
//My script is also set up to exec class-specific configs for each class, delete the exec *.cfg lines if you don't want this
//In order for the spawn point selection to work, you must also use et-spawn-select.cfg
//add the following line to your autoexec, "exec class-select-v7.cfg" and it should automatically load with the rest of your settings
//The first key press should always be =, that sets the main menu
//7 = spawnpoint select
//8 = team select and sets up the class and weapon selects - once you are on a team, you shouldn't have to touch this unless you change sides
//9, 0, and - class and weapon select a class
//Edited with secondary weapons of akimbo pistols and SMG, for soldiers
//1. Main Menu===============================================================
