Any ideas? I am attempting to write a script that uses sed.

If done this way it fails

rmdec="sed 's/..................$//'"
i1xmr=$(echo "$i1p/$apiresponse*1000" |bc -l |$rmdec)

But if i do it this way it works

i1xmr=$(echo "$i1p/$apiresponse*1000" |bc -l | sed 's/..................$//')

When using "<<-", shell removes all tabs from the beginning of each line. So you have to use tabs for formatting inside your script and then spaces for HTML formatting, as in my example. Or use "<<" without dash to preserve tabs.
