How can i do that

07106 = O:\BREZ\MSKAM\MSKWMF\M156.WMF
08124 = O:\BREZ\MSKAM\MSKWMF\M825.WMF
09210 = O:\BREZ\MSKAM\MSKWMF\M1480.WMF
92446 = O:\BREZ\MSKAM\MSKWMF\M793.WMF

And after i type 07106 in the text box and press buton it opens this file O:\BREZ\MSKAM\MSKWMF\M156.WMF or if i type value wich is not in that list it shows me ERROR ?
