Command to save in forms

Hi,

We have a custom form implemented early for our client. This form will not enable the submit button unless the users press the SAVE. This will make sure the data in the block saved successfully before submit, The submit button purpose is to invoke a workflow process.

Now the issue is, the users enter the data and the save. ->>> Here submit button now enabled.

Now user see a data had a TYPO and then correct the same and the press SUBMIT without SAVE... The last minute changfe (new corrected information) is not stored in to the tables. So we wanted to include a commit command when the submit button is pressed, so that it will ensure all final changes are saved.
