Simple DateAdd

Hi guys,

Can't find anything like this:
I have calibration intervals and need to calculate a due date:

Form 'control source'
[DueDate]=DateAdd("ww",[Cal Freq],[Date]) -

Cal Freq=weeks and [Date] in usual yyyy-mm-dd format.
Obviously Access needs a numerical in
[Cal Freq] 's place.

Any way to have it use a variable there queried from a column?

Thanks
Johan

SELECT dateadd("ww",[mycolumn],now) as Duedate from mytable;

Hi,

Thanks for the reply,

The answer was to obtain a field list setting instead of columns with:
SELECT dateadd("ww",[Cal Freq],[Date]) AS [Due Date] FROM [Cal Freq];

(all fields from a form!) and works perfect.

I had this as the control source in a 'text box' but find it can only be done with 'combo boxes':

Is there any way you can disguise a combo box to look like a text box? You can lock it - but can you hide the drop-down lip?

Regards

create a combobox and a list box and make it sync each other. and hide one of then which you dont wanna show.
