[RESOLVED] vb code to not run a macro if some cells are blank

Hi
in C9 user enters a customer number e.g. 124578

then in C10 user enters a date 16/3/2010

and from H20:H200 the user fails to enter required qty e.g. 2,5 or 100.

and runs a macro

when this happens the macro fails.

I want to stop the macro from being executed if all above 3 criterias are not fulfilled.

Can you please advise asap ... if possible.
Many thanks

assuming this is in excel

vb Code:

if isempty(range("c9")) or isempty(range("c10")) then exit sub
for each c in range("h20:h200")
  if isempty(c) then exit sub
next

this does not check for valid entries
you could change the first line to

vb Code:

if not isdate(range("c10")) or not isnumeric(range("c9")) then exit sub

Hi,

thanks again
regards

dim c as range

Excel VBA question moved to Office Development
