I am having following problem, hope someone could help me out.

I am using PHP code to retrieve product infomration via Merchandiser Query API web service. Among the data (product information) I retrieved, the linkurl data is incorrect in most time. Other data seem fine.

when the linkurl data is incorrect, the offerid parameter value will be
some thing like "offerid=0.28849", but correct data is
"offerid=62091.28849" (in case it is correct).

If post the query via my bwoser, it seem OK every time.

Please give some advice. You help is appreciated.
