smartforms

hai frnds

in a text element in smartforms there are 4 fields. if one of the fields is not printed i.e., if it is blank then i have to supress it. eg.,

field1

field2

field4

there is no value for field3

i want to supress this space in text element and print the field 4 in the next line. any suggestions are welcome and full points will be given. thank u
