need expression help/guidance

Do all expressions have to be on one line?
Can you declare variables in them like in Crystal Reports Formulas?
Can you use other formulas as values? As in you set up a textbox that
will give you a value with an expression, then in another expression
you reference the value of that text box?
Is there a decent guide out there for expressions? Why
can'texpressions just behave similar to a function?
The answers to this post will certainly help determine whether or not
we stick with Crystal or go with this.You can use GlobalVariables in RS :
In Report Properties, go in Custom Code and Declare typed Variables
Exemple : Public Test As String = "100"
You can reference this variables in any expression in your report :
=Code.Test
In any expression formula you can call Custom Code variables or functions.
As well as reference other Report Items:
=ReportItems!textbox4.Value (to use a textbox named textbox4 value).
Let me know if this helps.
