help with opening MAPPbuilder

[Jeanette Garcia]

I`m new using GenMAPP, well: trying to use it :(

I began to read the tutorial, i created the .txt file for the creation
of the mapp, but when i try to open de MAPPbuider from the gen mapp
windows, it shows me an error:

Run time error `13` :
type mismatch


I had not even use my file, so i think is not related with me the
error, or is it?
so i don`t know how to begin to use genmapp.

I have some expression microarrays and i already have the differential
expression 'gene lists. I understood that i have to create the mapp
using mapp builder with this txt file:

GeneID SystemCode Label Head Remarks MAPPName
NM_014892 Q RBM16 RetinoMAPP
NM_000817 Q GAD1 RetinoMAPP
NM_012262 Q HS2ST1 RetinoMAPP
NM_001941 Q DSC3 RetinoMAPP
NM_014260 Q HKE2 RetinoMAPP
NM_003204 Q NFE2L1 RetinoMAPP
NM_003336 Q UBE2A RetinoMAPP
NM_015669 Q PCDHB5 RetinoMAPP
NM_014893 Q NLGN4X RetinoMAPP

(Head and Remarks are blank)
and then in genmapp link this mapp with a human database. am i right?
or am i lost?

i need some advices, please.
