Syntax Error

IF(LastActivityDate <= 90 Day, checked = true, checked = false)
Can someone please help me with this formula? I am getting a syntax error and I think it might have to do with the day, but not 100% sure.

Ah I had a brain freeze there and compared the date value with a number. Sorry! Use the following: 
(TODAY() - LastActivityDate) <= 90

So I now have the formula as:

IF(DATEVALUE(LastActivityDate) <= 90, checked = true, checked = false)

and I am getting this error

Error: Incorrect argument type for function 'DATEVALUE()'.

I also changed it to 
DATEVALUE(LastActivityDate) <= 90
and received the same error message

Ah forgot that LastActivityDate is already a date field. Try this: 
IF(LastActivityDate <= 90,TRUE, FALSE)

You don't need the checked = true, checked = false,just TRUE and FALSE.
Also make sure that your formula field is of type checkbox.

IF(LastActivityDate  <= 90,TRUE, FALSE)
Error: Incorrect parameter type for operator '<='. Expected Date, received Number

What I'm hoping to acheive is it for it check the box if there has been activity withing the last 90 days.

I feel like we're so close!

No errors...yaaay!  Will this then check the box if there is activity within the last 90 days?

Yep. 
Last Activity shows when someone in your Organization last did something related to the record. It represents one of the following:
 
The latest Due Date of the closed tasks on a record. 
The latest Date of events on a record.
