Error ID

Hi I have a visualforce page where I made a input check box. I wan't to make another field required when this checkbox is NOT checked. 

Here's the part of VF code: 

<apex:pageblockSection id="ProjectInfo2" title="Project Site Contact Information" collapsible="true" Columns="2">
                <apex:inputField value="{!job.Project_Site_Contact_Name__c}"/>
                <apex:inputCheckbox label="Same as caller" onclick="{!SameAsCaller}"/>
                <apex:commandButton onclick="window.open('/apex/NewRecord','Popup','height=400,width=1000,left=100,top=100,scrollbars=yes,toolbar=no,status=no')" value="New Project Site Contact"/>
            </apex:pageblockSection>


Now I want to use something like:

<apex:inputField value="{!job.Project_Site_Contact_Name__c}" required='{!IF((!SameAsCaller == 'false'), 0, 1)}'/>

However, this is saying I'm providing text instead of boolean value. Is this even possible, if so how?

Please HELP! 

query like first check Partner level and depend on Partner Level , it will filter out Message for each Partner Level. It will be kind of dynamic SOQL with comparison kind of each values of Partner level.
[SELECT Id,Name, Channel__c,Partner_Level__c
                        FROM MessageAlert__c
                        WHERE Channel__c = 'Partner' AND
                        Partner_Level__c INCLUDES ('Diamond , Gold')];
