I tried to copy the first column of one worksheet into the first column of another. e.g. %(%Z,1)=%(T,1) sometimes simply doesnt work. What is the safest way to copy columns ? Thank you !
The string variable %Z is used by many Origin routines, so maybe it has been redefined by the time you try to copy it. The next time your copy command doesn't work type %Z= in the script window to make sure it's still what you set it to. I'd use another string variable in any case.
