Form Schedule Script Issue

Form Schedule Script Issue

I have set up a Form Scheule with the following script.

x = Daily_Test_Weight[Date_field == zoho.currentdate].count();
y = Daily_Test_Weight[Location == "DFW"].count();
if((x  !=  1)  &&  (y  !=  1))
{
sendmail
[
from:zoho.loginuserid
subject:"Daily Test Weight DUE!"
message:"Daily Test Weight due for today."
content type:HTML
]
}

It is set up so once a form is submitted the next day at 7am it will check to see if there is a record for the current date at Location."DFW"

If there is no record an email gets sent.

The script is working with one exception.  When I execute it I get this pop up.

Please enter the value for the input arguments:
this : Daily_Test_Weight  
Give value of the field ID, eg: 1000001,1000002,1000004,....
When I enter any value, it executes properly.

I attempted to use this script 

input.ID = "10001";

but learned that system variables can not be updated.

Does anyone know how to fix this?

Thanks,
Thomas
