Calling Functions Within Functions

This is my script for my function:

When I try to save it, it gives me the following error message:

Encountered "." at line 7, column 20.

Was expecting one of:

"(" ...

But I can save it as:

void both.AlpineFarm(int Id1, int ID)

{

ter = Alpine_Farm[Id1 = input.Id1].Id1;

tep = Alpine_Farm[Id1 = input.Id1].ID;

if (ter = null)

{

thisapp.edit.AlpineFarm(ter);

}

else if (ter != null)

{

thisapp.edit.AlpineFarm(tep);

}

Below I have supplied the script for both functions edit.AlpineFarm & add.AlpineFarm

void add.AlpineFarm(int Id1)
{
openUrl("https://creator.zoho.com/jpiajr/compost-tracker-supreme/form-perma/Alpine_Farm/Id1=" + input.Id1, "Same window");
}
void edit.AlpineFarm(int ID)
{
openUrl("https://creator.zoho.com/jpiajr/compost-tracker-supreme/Alpine_Farm/record-edit/Alpine_Farm_View/" + input.ID, "Same window");
}

Any ideas on why this is happening?

Also I have allowed access for support.
