Fetch data in different Applications

Fetch data in different Applications

Hello,

Working in Zoho connect I make applications in different groups according to the data access users are being given.
In Group1 their is AppName1 and AppName2 and have both different Forms from which MembersForm in AppName1
In Group2 their is AppName3 with an Form UserinfoForm that, as in AppName1, contains a LookupField 'Name' that links to AppName1.'Name' and gives a dropdown form names introduced in AppName1 - MembersForm.

My Problem is to fetch the data of other fields present in MembersForm to render them in fields of UserinfoForm.

What I tried is the example as in the countrys from ghsaviation at https://help.zoho.com/portal/community/topic/fetch-data-between-different-applications
The scripts are granted in both Applications but nothing is rendered when choosing a name in the dropdown of UserinfoForm.
This as what I did:

1) new function in membersForm :
string getPays(int varID)
{
fetPays = Les_GdS[ID == input.varID];
return fetPays.Pays;
}

2) On user input in UserinfoForm under Name:
if(input.Pays != "")
{
input.Pays = applications_du_gds.getPays(input.NOMPrenom);
}

Can someone help me out please ?

Thanks a lot !
