Smartform If statement

I have created a work address field for an employee on my smartfrom.

None of the fields are mandatory so i would like my form to remove a line/carriage return if the field is blank.

I have tried to do it this way using the command option

IF NOT &P0006-STRAS& = ' '

&P0006-STRAS&

ENDIF

IF NOT &P0006-LOCAT& = ' '

&P0006-LOCAT&

ENDIF

Etc.....

Is there an simple way to do this or am i missing anything that may be causing this not to work?
