Write statement for weights

Hi,

I am trying to display output using write statement for weights. This is my code:

WRITE: /05 TEXT-019. " Gross Wt

WRITE: 55 WA_MARA-BRGEW UNIT WA_MARA-GEWEI,

76 WA_MARA-GEWEI.

What am I doing wrong? The output does not show any values even though brgew has value 0.259. Please suggest. Thanks.
