Function error

I have a function, sort inside of a module, with parameters as such:

Public Sub Sort(SortCol As Integer, LastRow As Integer, Optional FirstRow As Integer = 1, Optional direction As String = "a", Optional index As Integer = 0)

I try to call this function from within a form as such:

something = Sort(location, grid.Rows)

where something is a variant.. it's not dimmed..
location is an integer
grid is a flexgrid

I get an error "Compile error: Expected function or variable".

What's wrong?  How do I call this function?

By the looks of the code (a FlexGrid sort).. it would appear that he does not need a return.. as the effects of what he is doing will be displayed in the FlexGrid.

If return information is NOT required.. then use the Sub as you have it.. and then use the following syntax:

Call Sort(location, grid.Rows)

If return information IS required.. then use a Function rather than a Sub.. as per the comments above.. <smile>.

you should declare it as a Funtion and not as a sub

If a function returns a value, you must declare it as a function, not a sub:

Public Function Sort(...
Sub don't return a value
you must use Function to return a value
Public Function Sort(SortCol As Integer, LastRow As Integer, Optional FirstRow As Integer = 1, Optional direction As String = "a", Optional index As Integer = 0) as Variant

As Variant is the type of value that the function return if not specified Variant is used. But it's always better to specify a real type.
powlin, RonaldBiemans AND Erick37 have already posted the same suggestion. According to EE "netiquette" you should not have locked the question. Would you kindly withdraw your answer?

Consider the condition that the function may return different data types depending on the parameters passed to it.  If this is the case, we do not want to implicitly define the return type, but can determine the type passed back later:

Public Function Sort(SortCol As Integer, LastRow As Integer)
    Dim sText As String
    sText = CStr(SortCol + LastRow)
    Sort = sText
End Function

Private Sub Command1_Click()
Dim something
something = Sort(10, 10)
Select Case VarType(something)
    Case vbEmpty
    Case vbNull
    Case vbInteger
    Case vbLong
    Case vbSingle
    Case vbDouble
    Case vbCurrency
    Case vbDate
    Case vbString
        MsgBox something & " is a string"
    Case vbError
    Case vbBoolean
    Case vbVariant
    Case vbDecimal
    Case vbByte
    Case vbArray
End Select
End Sub

You may a collision between your function name and another Sub or Function of another components.

You have 2 solutions:
-Change your function name
-Put the name of the module in front of the function name when calling it (something = YourModuleName.Sort(location, grid.Rows) )
Erick if you don't specify the type of the variable Variant is used. So
Dim something
create a variant
Public Function Sort(SortCol As Integer, LastRow As Integer)
return a Variant
why not specify it when you know what type is return.
