Hi:
Let's say that your variable CL_N is what you want with leading zeroes, then you would have 2 VAR statements:
[pre]
var CL_N / style(data)={htmlstyle="....."};
var CL_Nm REGION AssocNumeric;
[/pre]
The STYLE(DATA) override option allows ODS to pass the HTML style for CL_N (only) into the HTML that's being generated for the output file. The other VAR statement just lists the rest of the variables you want on the report.
