make script of repetitive task

Hi, I am novice to max scripting and I m wondering it there is way to make script button for some repetitive task in 3dsmax, as an example, i do lot of mesh cleaning for some imported objects many times, like..
----
"convert mesh to poly"
then select vertex mode - select all
then weld them to 0.001 threshold

then select Optimize modifier
select LOD - Face Threshold
Auto Edge

now select Edit Poly Modifier on that n "Collapse To"
----
I have tried Macro Recorder but it didn't work for me.
Please guide me how to do that thing n make button.
