date and time

[niquil]

Hello,

I have two drop down lists with times in it formatted this way:

HH:MM

Now I want people to tell me at what times they will be available.

So I made one dropdownlist with the start_time and one with the end_time.

So far so good but now I have people telling me they will be available from 18:00 in the evening till 10:00 in the morning instead of 10:00 in the morning till 18:00 in the evening.

In other words the end time should not be able to be earlyer then the start time.

How can I do this?

if $ddlBeginTimeSelectedValue < $ddlEndTimeSelectedValue 
{
echo "The start time should be earlyer then the end time";
}
else
{
//my statement to put the times into my database
} 

This is not quite enough.

I would GREATLY appreciate any help I can get!

thank you...
