>>Andy,
>>Why are you not using date or datetime in your SP to prevent ambigiuties? Anyway if you want them as strings you can have them as strings like that. First decide what does '02/01/2009' mean. Say, if it is Feb 1, 2009 and you have set date to mdy then you could construct the string in VFP like this:
>>
>>
ldStartDate=thisform.startdate.value
>>ldEndDate=thisform.enddate.value
>>
>>lcStartDate = dtoc(m.ldStartDate)
>>lcEndDate  = dtoc(m.ldEndDate)
>>lcSQLCMD="exec get_invoices ?m.lcStartDate,?m.lcEndDate"
>>SQLEXEC(gnConnect,lcSQLCMD,'jobcost')
>>
>>PS: It is better to have date/datetimes as date/datetime on both sides instead of doing character conversions.

I am not sure I understand. A date would be passed as a datetime parameter. Internally a date like 1/1/2000 is considered to be a datetime value of 1/1/2000 00:00:00 (or 12:00:00 AM).
