excluding null value in a string

[BlurredVision]

I am attempting to get a minimum total going on a string field. There are some null values within the string field which mess up my minimum total. Is there a way around this?

Thanks for your time...

not sure how you are going about this but to eliminate NULLS

use: {@fieldtest}
*****************************************************
if not isnull({table.field}) then
{table.field}
else
""; //put a value here tah does not interfere with
your minimum calc

*************************************************

then you can do a summary on this field

minimum({@fieldtest})
