Invalid left-hand side in Assignment Error message when clicking custom button
I created a custom button that sends out an E-mail whenever it is clicked. It was working fine until I added a new logic to not let it function when it is clicked more than once.
Original code:
if('{!QA_Release__c.Client_Site_Type__c}'!='' && '{!QA_Release__c.Time_for_Upgrade_Update__c}'!='') { location.replace('/email/author/emailauthor.jsp?saveURL={!QA_Release__c.Id}&p3_lkid={!QA_Release__c.Id}&rtype=003&p2_lkid={!QA_Release__c.Assignee__c}&p24=support-sentrydevelopment@clearstructure.com&p4={!QA_Release__c.Cc__c}&template_id=00XC0000001Suga'); } else alert('The "Installation Type" and "Upgrade/Update can be done" fields both need to be filled in order to complete this action.' ); }
I now added a custom field called Is_Mail_Sent to my custom object and the idea is to have a default value of 0 for this field whenever a record is created. When someone clicks on my custom button , it should send out an E-mail and set Is_Mail_Sent to 1. If someone tries to send out an E-mail again , I check if Is_Mail_Sent =1 and if it is 1 , no email should be allowed to be sent.
if('{!QA_Release__c.Is_Mail_Sent__c}'!=1) { if('{!QA_Release__c.Client_Site_Type__c}'!='' && '{!QA_Release__c.Time_for_Upgrade_Update__c}'!='') { location.replace('/email/author/emailauthor.jsp?saveURL={!QA_Release__c.Id}&p3_lkid={!QA_Release__c.Id}&rtype=003&p2_lkid={!QA_Release__c.Assignee__c}&p24=support-sentrydevelopment@clearstructure.com&p4={!QA_Release__c.Cc__c}&template_id=00XC0000001Suga'); } else alert('The "Installation Type" and "Upgrade/Update can be done" fields both need to be filled in order to complete this action.' ); } else alert('Someone already sent an E-mail to support for this task. You cannot perform this action again.' ); '{!QA_Release__c.Is_Mail_Sent__c}'=1;
I get Invalid left-hand side in Assignment Error message when I click custom button even for the first time. Can someone please help me know what's wrong?
By reading the first and last lines of your updated code, I assume that QA_Release__c.Is_Mail_Sent__c contains values like null, 0 and 1. If this is true, than your last line renders to:
which is would give you the Invalid left-hand side in Assignment Error.
Try this:
This will work until the page is reloaded. To make it permanent, in emailauthor.jsp you will also need to update the record's Is_Mail_Sent__c field to true.
