Record number, start column, and length not provided for <INSERTPAGE>/<INSERTREC> varname.
What happened: You set the Variables group <VARTYPE> tag type parameter to FLAT, indicating that variable values could be found in a variable flat file, but you did not specify record, column, or length values for an <INSERTPAGE> or <INSERTREC> tag. The varname value of the errant <INSERTPAGE> or <INSERTREC> tag is given.
What to do: Make sure each <INSERTPAGE> or <INSERTREC> tag has a varname, source, record, column, and length value. If your variable file is actually a variable definition file, change the <VARTYPE> tag type value to DEFINITION.
