Scripting • Change line/wall light via ACS?

Code:

int test = 93;      // TID of the fist line.    //I've made a dummy sector with brighter light and set it to line 93 via Transfer Wall Brightness.Script "LightTest" (void){Test++;SetLineSpecial (430, 16, test, 5);      // 430 is the TID of the line with the Transfer Wall Brightness special      // I was hoping to change the line's special and set the TID of the next wall to get brighter.}
