Visualforce reading field as an object

Question

I've been banging my head against a wall for this and can't seem to figure out this error. VF seems to be reading my field as an object.

Here is my code

LineitemNumber: <apex:outputText value="{!(NOW()-object.LastModifiedDate)*24*60*60}"></apex:outputText>

Here is the error: "Error: Incorrect parameter type for operator '-'. Expected Number, Date, DateTime, received Object"

How is VF reading the field as an object?

I am not, I'm getting it from a controller. from my controller, it is called lineItems. What is weird is that I tested it with another object that I pull LastModifiedDate from and it works just fine. It just won't read with this object. — Andrew, Jul 21, 2016 at 22:59
I found something similar in this link, except it is with a different error: salesforce.stackexchange.com/questions/9482/… — Andrew, Jul 21, 2016 at 23:02
Maybe that is what I am not understanding. LineItems is the object but when I think datatype, I'm thinking LastModifiedDate is the field with datatype of DateTime. — Andrew, Jul 21, 2016 at 23:10

This code works in my org:

<apex:page standardController="Account">
    {!(NOW()-Account.LastModifiedDate)*86400}
</apex:page>

(It also works with apex:outputText).

Check the data type of the variable you're referencing, and make sure you're referencing the correct variable.
