a touch script help please

i am trying to mod a script so that i can set it in something and with each click make it cycle thru frames of a texture then after the last on go back to the fist frame. i got this far but cant figure out how to get the send list to read and i can figure out how to get the floats into where they need to be which would be in a lloffset statement instead of the llsettexture that is there now. i really thought this was gonna be easy but my head hurts just reading the stuff in the wiki LOL.

any help would be greatly appericated

and yes i know they are all the same float value i would change it later

integer frame;

// This list is for the (U) of the horizontial offset of thetextures to display. The list will
//  start on the top and work its way down.
list Uhorzoin =
        ["-0.210", // frame 1
         "-0.210", // frame 2
         "-0.210", // frame 3
         "-0.210" // frame 4  Do not place a comma after last texture
         ];
         
// This list is for the (V) of the verticle offset of thetextures to display. The list will
//  start on the top and work its way down.
list Vvert =
         ["-0.210", // frame 1
         "-0.210", // frame 2
         "-0.210", // frame 3
         "-0.210" // frame 4  Do not place a comma after last texture
         ];
                  
display()
{
     //  This two IF statements check to make sure the current page is
     //  a valid frame number according to available frame
    if(frame < 0) frame = 0;
    if(frame > llGetListLength(Uhorzoin) - 1) frame = llGetListLength(Uhorzoin) - 1;
    
    //  this extracts the current frame out of the list
    string textur = llList2String(Uhorzoin, frame);
    
    // Here we set the texture only on the face of the book and nowhere else.
    llSetTexture(textur, ALL_SIDES);
}
default
{
    touch_start(integer num_detected)
    {
        
        display();
    }

   
}

there's already a script out there that can do that.

i can give it to you next time i'm in world if you like.

AWSOME
thanks loads and loads

thou i appericate your scripts you gave me its not what i was looking for .
i want to change the offset of already textured object using a list of coords of float values to do this.

after a bit of tweeking and looking at some other scripts i found out how to make this do what want it tod do which is to get the information from the same line of 2 lists and use it as a float to input it then into a llOffSet function and its workign beautifualy thanks for the help
