textmesh OnTriggerEnter

Hi Sry for being thick Im trying to use the textMesh "simple code" example to get the score to add up in the textmesh. when ever i trigger. the score code works in the Update but if i put it in:

if (m_triggering) { blah score dam you blah} it stops working.

or even if i put it in:

void OnTriggerEnter(Collider other) it stops as well.

Any ideas please.
