I have XPath with two parameters. but when I call it to script how can I pass parameters?

I passed as below
_WebUI.click(findTestObject(‘Object Repository/Page_GS_RoleAndPermission/chk_PermissionsWithParent’,[(‘parentPermission’):permissionCombination[0]],[(‘childPermission’):permissionCombination[1]]))
_
Note: “permissionCombination” is an array
but it giving an error
Error : No signature of method: com.helper.common.CommonFunction.findTestObject() is applicable for argument types: (java.lang.String, java.util.LinkedHashMap, java.util.LinkedHashMap) values: [Object Repository/Page_GS_RoleAndPermission/chk_PermissionsWithParent, …]
Please help on this.
Thanks.
