Creating a Custom Log a Call Button

I want to create a custom button that when you click on it opens the Log a Call window. However, I cannot figure out how to get the code to work properly. This is what I have done so far:

{!LINKTO('Log A Call', '$Action.Activity.LogCall', '$ObjectType.ActivityHistory')}

Am I doing this correctly?

Hey Karin,

All depends on how you want this link to display. I am a huge fan of creating a button (similar to the log a call button). What you need to do is create a URL that will pass through the information that you are looking for. 

Send me an email to 
We can set up a screen share and I can walk you through making a completely functional custom button that can prepopulate pretty much anything!

Best of luck!

try this url, change xxx to your salesforce instance{Account.Id}&followup=1&tsk5=Call&retURL=%2F{Account.Id}

Using whatid={!Lead.Name} wouldn't work, you need to specify what the field is equal to...

For instance for a lead you have to use:
&tsk2=00Q for leads

Just an fyi!

@Johan - best practices when creating a url that points to Salesforce is to leave off the part of the link. If you just use /00T/e, it will be smart enough to us the right instance. This is really helpful when going from Sandbox to Production or if Salesforce ever decides to move you to another instance.

@Daniel, you are right on eliminate

@James, yes, not to combine what_id and who_id, it depend on what object it should call from.

@Karin, you can just simpley use to point to URL '
/00T/e' for general usage.
