>>>Well this is the thing now. I've replace the thisform.dStartDate with ldDate in this code, now I'm back to square one in that when I drop ythe combo (1st time) I get message that ldDate not known. Trouble is that code is supposed to fire when I change the operator (also via combo); this isn't happening when I drop the Route combo.

>>>The filter assignment is now simply:

>>> lcFilter	 = "OPERATOR = " + ALLTRIM( STR( lnOperator)) + " and " + ;
>>>  		      "END_DATE >= ldDate or EMPTY( END_DATE)"

>>>Can't figure why this fires at this point cos, as I said, I'm not changing the operator.

>>Because you have to put it as a constant, not the ldDate variable as you show here. See my other reply to Borislav (cc to you) a sec. ago.

>Yes, thanks Naomi. See - I don't know why this on-change-of-operator code is being fired, when I click (only 1st time) on the route combo. I just get the error message immediately, bypassing debugger. If this code were to fire properly then no matter which format I use (I can sort that out) the var will be properly assigned.
