thank you

As described into the documentation, the name and index properies in colModel can not contain spaces.

Regards

colModel:[
      {name:'ID',index:'ID', width:250, label:"ID",hidden:true,key:true},
      {name:'CertName',index:'CertName', width:250, label:"Cert Name",search: true, searchoptions: { sopt: ['cn','eq', 'bw', 'ew' ]}},
      {name:'CertExpires',index:'CertExpires', width:90, label:"Expires Date",formatter: ColorDateformatter, search:false},
      {name:'CertDate',index:'CertDate', width:90, label:"Cert Date",formatter:"date", formatoptions:{srcformat: 'Y-m-d',newformat: 'm/d/Y'},search:false},
      {name:'per Name',index:'per Name', width:190, label:"Name",search: true, searchoptions: { sopt: ['cn','eq', 'bw', 'ew' ]}},
      {name:'LeadName',index:'LeadName', width:170, label:"CrewLead",search: true, searchoptions: { sopt: ['cn','eq', 'bw', 'ew' ]}}
      ],

and here is my toolbar 

        .jqGrid('filterToolbar',{stringResult:true})

When i try to search any field i get this error

     "uncaught exception: Syntax error, unrecognized expression: [name=per Name]"

i only get this error on the search toolbar.  i can use other forms of search and it works fine.  changing the "per Name" index, and my data feed to "perName" corrects this error and the search works fine
