Objects Not Working In Sub - function

Question

In our code, we have a few Excel objects and a few subs and functions.
We edited a few things and now, for some reason, our objects aren't working inside the sub, the give a "Object Required" error.
We don't know what to do anymore, so any help would be greatly appreciated!
Note: We added the entire code in case there would be questions about declarations and that...
Sub:
Sub birthday (formatDate, i, intRow)
'Take date from database, separate it to days & months
Dim month, day, name
eventDate = Split(formatDate,"/")
month = eventDate(0)
day = eventDate(1)
'Get name of event out of database (one column to the right, from date of event)
name = "netch"
'Get value of row which is used to write events in the specific month
Dim k, row, c
k = 1
wscript.echo objXLCal.Cells(k, 2).Value
Do Until objXLCal.Cells(k, 2).Value = monthRet(month)
k = k + 1
Loop
'k will be used to find the day column, while row is where the events of that months are written
row = k + 3
c = 1
'Get value of column
Do Until objXLCal.Cells(k,c).Value = eval(day)
c = c + 1
Loop
'Insert name of event into place
If Asc(name) = 63 Then
objXLCal.Cells(row,c).Value = StrReverse(name)
Else
objXLCal.Cells(row,c).Value = name
End If
End Sub
Rest of code:

Another function:
Function monthRet(month)
Select Case month

monthRet="January"
Case "2"
monthRet="February"
Case "3"
monthRet="March"
Case "4"
monthRet="April"
Case "5"
monthRet="May"
Case "6"
monthRet="June"
Case "7"
monthRet="July"
Case "8"
monthRet="August"
Case "9"
monthRet="September"
Case "10"
monthRet="October"
Case "11"
monthRet="November"
Case "12"
monthRet="December"
End Select
End Function
Thank you very much!

Answer 1

Given a code layout like:
Sub birthday (formatDate, i, intRow)
...
wscript.echo objXLCal.Cells(k, 2).Value
...
End Sub
Function main(argFilePath)
...
Set objXLCal = CreateObject("Excel.Application")
...
End Function
main "C:\Users\liatte\Desktop\hotFolder\Input"
an "Object required" error for the WScript.Echo line is to be expected (the local variable objXLCal initialized in main isn't the same as the (therefore) uninitialized local variable objXLCal in birthday).
The correct solution would be to start with "Option Explicit" and follow the principles of decent procedural programming in VBScript, but the disgusting hack of Diming variables like objXLCal at the top/global level won't lower the quality of the published code.
