Hi,

I'm fairly new to sharepoint 2003, and I've got a question, probably it's easy, but please if someone can help me with a efficient solution. Thanks!

I have 6 data sources (they all textbox), they are called: num1, num2, num3, num4, num5, smallestNum.

I just want the smallestNum to automatically find out the smallest number out of the 5 numbers and display it.

And these 5 numbers could be null, could someone please also tell me how to check null as well? and can all these calculation be done in sharepoint2003? or do I need to write some Jscript code?

Thanks so much!!
Kris
