glm question

Dear All, I?m running a glm with poisson errors and have a doubt when
ploting the predicted values. One of my variables has a positive slope in
the summary output, but when I plot the predicted values on the original
plot it draws a line with negative slope. I appreciate your comments on
this and any other aspect of the analysis.

Attached is the script and data.

Thanks in advanced,

Joaqu?n.

pd. If this is not the correct forum to ask about glm, please let me know.
