Problem with ctl file

[luis blacutt]

Dear Grads users,

I'm writing a ctl file to open 24 (only 24) files,

baseline1pmg2jantp.grb
baseline1pmg2febtp.grb
baseline1pmg2martp.grb
.
.
.
baseline1pmg2janpr.grb
baseline1pmg2febpr.grb
baseline1pmg2marpr.grb
.
.
.

my ctl file is as follows:

dset ^baseline1pmg2%mctp.grb
index ^baseline1pmg2%mctp.grb.idx
options template
undef 9.999E+20
title Temperature at 1.5 m
*  produced by LFA 0.3
dtype grib 255
options yrev
ydef 37 linear -23.960000 0.439
xdef 36 linear -72.240000 0.440000
tdef 12 linear 00Z01jan1962 1mo
zdef 1 linear 1 1
vars 1
s03236  0 236,105,0  **
ENDVARS

As for now I'm trying to open only 12 files, with one variable, the error I
get is:

Scanning description file:  first.ctl
Open Error:  Can't open Station/Index map file baseline1pmg2%mctp.grb.idx
  The data file was not opened.

Thanks
Luis
