Warning text where any tokens have been already substituted is more useful to identify what bit on the target is wrong (e.g. if RRD file, wrong filename).
For example, $target[4] may contain "{link:this:name}.rrd", whereas $targetString would contain the string after substitution (e.g. "router1-interface-ae0.rrd")
