Are you using a variables (v) parameter? In the case you describe, you would normally use (v2) to indicate that you have 2 variables to record. Your would then use <ml.varname>_01 and <ml.varname)_02 to refer to those two variables in your HTML code. OR you could refer to them explicitly as relig_01 and relig_02.

Note: Normally, if you have just one variable, you can skip the v parameter and just use <ml.varname> or, in this case, relig.
