Try this: on mouseup repeat with x = 1 to the number of lines in fld "test" if last char of x is in "02468" then set the backcolor of line x of fld "test" to "218,255,255" end repeat end mouseup For these even colored lines, you'll have to type spaces all the way to the end of the line, because as soon as there is no text, the backcolor stops. Hope this helps Fred Moyer
