Trigger for 75% usage?

[pcpolo]

Can someone help me out to create a trigger for a Cisco router when 75% usage of an interface is being used?

Essentially we want to know when 75% of a set amount of bandwidth is being used.

{cisco:Port_E1_0_3_0_OutOctets.min(#4)}>0.75*{cisco:Port_E1_0_3_0_Speed.max(#2)} & {cisco:Port_E1_0_3_0_Speed.max(#2)}#0
