Run Macro When Range Value Not Blank, If Not Run Other Macro First

I wanted to modify the below macro but don't know how. Could someone help me please? Please see the bold text below.

Dim shortmonth As String
Dim todaysdate As String
Dim enterdate As String
'GET DATE AND CREATE VARIABLES
enterdate = InputBox("Please enter the date in the following format: MMDD")
shortmonth = Left(enterdate, 2)
todaysdate = Mid(enterdate, 3, 2)

Workbooks.Open Filename:= _
"S:CMU Trade VerificationTrade Discrepancy Report " & [shortmonth] & " " & [todaysdate] & ".xls"
Sheets("Daily Archive").Select

***Do this step when when range A2:N2 is not blank, otherwise, run the "Daily Data" macro first and then do the below steps.
