The problem is that your clipboard value has a carriage return and a line feed (a ENTER with a new line). When you assign this to the variable %string% you are assigning this carriage return/new line to the variable also.
I kind of suspected that too! And yes, u r right! I tried to copy carefully without copying the linefeed/return "end space" from wordpad and it seemed to work better as expected! Tks so much Steve! U r brilliant! Anyway to deal with that in MMM? Anyway to ignore that LR or CR character? Tks!
