Rotation script commande help plz!

okay so i am REALLY noob to scripting and i want to know how to do something specific so id appreciate it if you guys could help me out

ive got this script from someone and it makes your tail wag, everthing is fine, but i want it to happen (wag) only on a certain command, in short i want it to happen only at certain time when i use the /1command. i tryed to look around but all i made was some nasty syntax errors .. hehe

thank you!

vector start;
tailwag()
{
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <-20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <-20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <-20, 0, 0>)));
        llSetRot(llEuler2Rot(DEG_TO_RAD*((RAD_TO_DEG*llRot2Euler(llGetLocalRot()))+ <-20, 0, 0>)));
