Ok so I took my map and compiled it all in CoDUO Maker and when I press launch the game says
max ammo mismatch: for smoke grenade ammo: flashgrenade_mp set to 3 but flashbang_mp already set to 999.
Can you guys please Im confuzed

this has nothing to do with coduomaker

the error is caused because you have a mod in your resource folder that is modifying the grenade count

remove it (the mod) and the error will go away

i have also had custom maps in my uo or cod folder give me off the wall errors before.

Ok I fixwd ir butI face another problrm...When Im in the map I go through the street if go crouch I can below my map..Though that is only the street the sidewalks are perfectly fine...

Heres what I mean

the only error i can detect from your screenshot is some texture stretching on the wall...but if you are below the street texture...then i would suspect that you have used an alpha texture

change the texture you are falling through to one with an "@" in the name, which specifies that the texture has a shader...which 90% of the time signifies that it is solid
