[esp-r] pressure coeffcient calculation error

[NALIN SWAROOP]

Hello all
I am trying to calculate the pressure coefficients from esp-r but every
time a enter a coordinate for calculation and try to calculate the coeff.
and then enter it to a new database it gives me the following error
failed in ../zones1floor_e.geo conversion of no. press item value in -1.00
In ..zones/1floor_e.geo error reading press db ln1 EOF sensed

Why is it opening the geometry file??
What can be the problem??

Regards

Nalin
