Passing key fields to other forms as a global variable

Passing key fields to other forms as a global variable

 I just started with Zoho Creater this morning - it seems like fantastic scalable application !!. !

I am having problems with creating a common key field called DEAL_ID and using this to pass to other Forms  as the key field.

I have tried various ways such as using a script on the form called New_Deal

DEAL_ID4 = input.ID + "_" + input.Deal_Name;
share form("application", DEAL_ID4);

But this does not seem to pass the DEAL_ID4 variable to any other Forms in my application ?

Would appreciate any answers or suggestions ?

thanks
