I am having trouble with the syntax on the following calculation. Evidently, I am not structuring the command as needed by fox.

any suggestions?

Thanks in advance.
Brad.


thisform.olecontrol1.PortOpen=.T.
if thisform.olecontrol1.portopen=.t. then
messagebox ("The Port is open, Ready to Send this Part Number to the Saw.")
endif

thisform.olecontrol1.output="motest"+chr(13)

M=thisform.txtColumn3.value

Mc=(m)* -1 *THIS IS WHERE I GET THE ERROR***

messagebox (M)


thisform.olecontrol1.output="D"
thisform.olecontrol1.output=(Mc)
thisform.olecontrol1.output=chr(13)



thisform.olecontrol1.output="GO"+chr(13)


thisform.olecontrol1.PortOpen = .f.
if thisform.olecontrol1.portopen=.f. then
messagebox ("The Port is now closed")
endif
