Also of note, the 'return $sqltoday' line will return the first element of the final line of your '$dbhdt->dbnextrow' query. For example if the data were like this:

Field1 Field2 Field3
bill   smith  32
bob    jones  43
[download]

your return would be 'bob' If that final line had no value in the first position you would return nothing, like this:

Field1 Field2 Field3
bill   smith  32
       jones  43
[download]

this would return '' in '$sqltoday'; Note, this is just a guess since I do not know your data setup. -Chad
