[Object collision counter with color change]

So I was over killing it and made mistakes *flops about* I have been pulling my hair out trying to figure out what I did wrong.Thank you <3

[Object collision counter with color change]

I am trying to make a target system where I shoot it up to five times each time shows a new color, on the 5th time reset the counter and start fresh with it going back to white.

 

this is what I have thus far but it's getting stuck on the 5th color and not working from there.

default
{
    state_entry()
{
    }  
     collision_start(integer number_detected)
{
    llSay(0, "Ding!");
    {
    integer i;
    for( i = 0; i < number_detected; i++ )
    {
        if(i=1)
        {
            llSetColor(<1,1,0.0>, ALL_SIDES);
        }
        if(i=2)
        {
            llSetColor(<0.0,0.0,0.0>, ALL_SIDES);
        }
        if(i=3)
        {
            llSetColor(<0.0,0.0,1>, ALL_SIDES);
        }
        if(i=4)
        {
            llSetColor(<0.0,1,0.0>, ALL_SIDES);
        }
        if(i=5)
        {
            llSetColor(<0.5,0.2,0.0>, ALL_SIDES);
        }
        if(i > 5)
        {
            llSetColor(<1,1,1>, ALL_SIDES);
            llResetScript();
        }
    }
    }
}
    collision_end(integer number_detected)
    {
    }
}
