Does a basic validity check of the current form.

Verifies that the current form does not have:

• A variable that is located twice on the form.  For example, if you have cell A1 linked to Influent Flow (Day 1 of the form) and cell B5 linked to Influent Flow (Day 1 of the form) when saving data when using the form OPS would not know which value to save.  Therefore, the form is not allowed to be saved with this condition.
• A cell linked to a calculated variable with a formula in the cell.

EXAMPLES:

Example 1: Form passes all tests and can be saved:

Example 2: Duplicate Variable Reference:

Example 3: Calculated variable cannot have a formula in the cell.
