I need help with the a vlookup formula that needs to use wildcards.

Sheet 1 has the following columns:

MSO# ORDER
NQCT8 111
NQCT8 222
NQFH4 333
NQFJ6 444
NQXF0 555

Sheet 2 has the following columns:

TRKCASE ORDER
JVB65/NQXFO/Z1R09148 555
JVB65/NQCT8/Z1K05629 222
JVB65/NSTB4/Z1R09145
JVB65/NTDZ9/84EX00053
JVB65/NTZS1/Z1K05424

I need a vlookup function in the ORDER column in Sheet 2 that will look to
see if the TRKCASE in the same line matches any of the MSO#'s in Sheet1 and
if so, enter the ORDER # from Sheet 1. What's confusing me is that the MSO#
from Sheet 1 will be inside TRKCASE. I've included what ORDER #'s should end
up in the ORDER column in Sheet 2.

I appreciate the help. Thank you!
