ERROR: invalid parameters for Template:Ifexpr:
{{Ifexpr...|{{{3}}}|{{{1}}}|{{{2}}}}}
Check for invalid numbers, or parameter 1 must be empty when using "1=" format.
The Template:If/errmsg is used to display advisory messages for either the Template:If or also for Template:Ifexpr which can process if-expressions without removing the leading or trailing spaces within then/else clauses of the logic.
- Usage: {{If/errmsg |{{{2|}}}|{{{3|}}}|{{{1|}}}|t=templatename}}
The template passes the values of parameters {1}, {2}, {3} and {t} (the template name, such as t=Ifexpr) so that they can be displayed to clue the reader into spotting which instance (of using Template:If or Template:Ifexpr) had triggered the message.
