Material Question

[spamclark15]

Dealing with materials, I'm trying to rewrite the gui/hell/stamina material to scroll only a single TGA but getting it to do 3 things simultaneously, that is, scroll, have translucency, and exist within the box for stamina is proving to be difficult. Currently I have it written:
 

gui/hell/stamina
{
    {
        blend    blend
        map        guis/assets/hud/mp/lstafill2.tga
//        colored
    }

    {
        maskcolor
        map        guis/assets/hud/mp/lstafill2.tga
        scroll time * -1, 0
//        colored
    }

This reuses the top part of the original code where lstafill2.tga has an alpha channel the shape of the stamina bar. Since I don't want all the effects that the original material had which combined more than one image together, this has been a challenging material to figure out so I'm sort of lost at this point.
