Thanks once again schaefer for the reply,I tried adding the code above to the script I have but it seemed to error in mirc no matter what line I move it too(prolly just me adding it in wrong place etc).

None the less with some playing with the filter line I have already in the code I managed to get it to lock onto the "a EST" and p EST" part of [11:07:52p EST] and not block words like best,desttination etc.. smile
