Having problem with sprites using blizz abs 2.84

[Travis]

Hello guys,
As I am doing project basing on modern war I used guns with ammo. The problem is when I shoot the pistol there is just the same sound which appear when I push the skill bottom. It didn't show the shooting sprite and projectile sprite. It's not using the weapon, it's just the sound come out. By the way, I configure the weapon as Bow and arrow which consume pistol ammo. Another problem is when I put the running sprite and run it shows this error. "Script Part 3, line 1222. NoMethodError occured. undefined method '-' for nil:NilClass."
I am just trying to finish all the battle systems and graphics for my project before I return my home country as I will not be able to access the internet well in my country. Please help me guys.

Thank You So Much.

Check all your configurations in the script and within the database again. See that all your sprites are there, all the necessary action sprites are enabled and the actors are configured to use the action sprites, check how your weapon is configured, and check the skill tab, etc.

As for the second error: http://forum.chaos-project.com/index.php/topic,106.msg175692.html#msg175692

I see.. Thanks a lot for the help and many thanks for always helping me  .. I have one more question by the way. When I use the weapon sprite and shoot, the sprite appear at lower place than the normal standing which looks a little bit weird and ugly. For me I do something like.. i just put blank for the char_atk1 and put different sprite for char_wpn_1. I do so because for my character the appearance when my character shooting a shotgun and when he holding a pistol is different. That's what I am encountering currently.

Please help me if you have free time. 

Thanks a lot for helping me when I face with errors.

Sounds like more of a graphical issue than a script issue. Give me a screenshot of what it looks like and your character set file(s)--in spoilers of course.
