Need help with auto populating and filling subform

Need help with auto populating and filling subform

PROBLEM: We have a form named "Add_Program" and within that form we have a subform named "Services". Within the main form "Add_Program" we have a dropdown field named "Program". If the user selects "Cleanup" from that dropdown, the subform should autopopulate the rows in the code below. However, we're receiving an error code:

Error details:
 Error in executing On User Input script of Program.
 Invalid update task found corresponding properties Line:(5)

---------------------------------------------------------------------------------

Main Form Name: Add_Program
Subform Name: Services

if(Program == "Cleanup")
{
row1 = Add_Program.Services();
row1.Included="True";
row1.Service="Winter Cleanup";
row1.Price="200";
input.Services.insert(row1);
row2 = Add_Program.Services();
row2.Included="True";
row2.Service="Spring Cleanup";
row2.Price="375";
input.Services.insert(row2);
row3 = Add_Program.Services();
row3.Included="True";
row3.Service="Spring Mulch Application";
row3.Price="375";
input.Services.insert(row3);
row4 = Add_Program.Services();
row4.Included="True";
row4.Service="Landscaping Maintenance Visit";
row4.Price="200";
input.Services.insert(row4);
row5 = Add_Program.Services();
row5.Included="True";
row5.Service="Fall Cleanup";
row5.Price="375";
input.Services.insert(row5);
row6 = Add_Program.Services();
row6.Included="True";
row6.Service="Fall Mulch Application";
row6.Price="375";
input.Services.insert(row6);
cleanup = Collection();
cleanup.insert(row1,row2,row3,row4,row5,row6);
input.Services.insert(cleanup);
}


Thanks for your help!!! Chris
