Populate 2nd combo box based on value selected in 1st combo box

Question

I am still using Acrobat 6 though I may be upgrading soon to Acrobat 8. I have a form with two combo boxes, the first "state" has values of MN and WI. Based on which value the user picks I would like to populate a "county" combo box with lists of counties that we deal with.
Thanks,
Gene

One can set the option and export value using an arry:<br /><br />// document level script<br />// Master List of Lists <br />// Each entry in this object listeral is the name of a State <br />//Manually enter the State Names into the state field combo box <br />// The associated value is the item list, where each item is a name value pair, [<County> and [county code, zip code]] <br /><br />// state: ["county name", ["county code", "zip code"]]<br />var oStateNames = {MN: [["-", ["", ""] ], <br />                       ["St. Louis", ["MNStl", "55001"] ], <br />                       ["Carlton", ["MNSCrl", "55002"] ], <br />                       ["Pine", ["MNPin", "55003"] ],<br />                       ["Cook", ["MNCok", "55004"] ] <br />                       ], <br />                   WI: [["-", [" ", " "] ],<br />                        ["Douglas", ["WIDou", "55005"] ] ,<br />                        ["Bayfield", ["WIBay", "55006"] ],<br />                        ["Burnette", ["WIBur", "55007"] ],<br />                        ["Ashland", ["WIAsh", "55008"] ]<br />                       ]<br />                     }; <br /><br />//SetCountyEntries() on keystroke entry in state field <br />function SetCountyEntries() <br />{ <br />   if(event.willCommit) <br />   { <br />      // Get the new counties list from the Master List <br />      // Since the selection is being committed, <br />      // event.value contains the State name <br />      var lst = oStateNames[event.value]; <br />      // Clear the county list if there are no counties for the selected state <br />      this.getField("ee.address.county").clearItems();<br />      this.resetForm(["ee.address.code", "ee.address.zip"]);<br />      if( (lst != null) && (lst.length > 0) )<br />           this.getField("ee.address.county").setItems(lst); // set opiton and export value<br />   } <br />} <br />//  end document level script<br /><br />For the combo box "ee.address.county" one can create an array from the export value to populate the county code and zip code<br /><br />// custom keystroke for county combo box<br />if(event.willCommit & event.value != "") {<br />// split county and zip codes<br />var aCodes = this.getField(event.target.name).value.split(",");<br />this.getField("ee.address.code").value = aCodes[0];<br />this.getField("ee.address.zip").value = aCodes[1];<br />}<br />// end custom key stroke code
