YAY! I really did cheer...people in the office are looking at me strangely now. :)
No matter, as I have finally got my IP 2010 form functional now! I will pass on my findings, which may prove to be interesting.
I have a lot of information that needs to be populated on my form, so I spent time formatting it so it could be just submitted as is, without having to recreate another view.
1. Right click on the background, select View Properties and under the General tab/Layout Settings set a custom layout width.
2. Statically set all object widths with pixels not percentage as Joy_T described.
3. I have 1 table which includes all of my form content, and I created a new section below it. Cut and pasted the table into the section.
4. Copy and paste the section. Now I have 2 sections with my form displaying twice. ( Note that not all controls store duplicate data, specifically the Option Button object. )
5. For the Date Picker object and for the Option Buttons, I replaced those in the 2nd section with text fields which pull values from the 1st section.
6. Using Hilary's solution, I created a boolean field called IsEmailing and set it to FALSE. (note the default capitalization of FALSE and TRUE)
7. Select Section 1 and create a Formatting Rule. Condition: IsEmailing is equal to TRUE. Rule Type: Formatting, select Hide this control.
8. Select Section 2 and create a Formatting Rule. Condition: Is Emailing is equal to FALSE. Rule Type: Formatting, select Hide this control.
9. Under the Data tab on the toolbar, select Submit Options and select 'Perform custom action using Rules. Now select Form Submit in the Rules grouping
10. Now to create 3 action rules... Rule 1 - Condition: IsEmailing = FALSE, Rule Type: Action, Run these actions: Set a field's value IsEmailing=true (lower caps)
11. Rule 2 - Condition: None, Rule Type: Action, Rune these actions: Submit using Email Data Connection
12. Rule 3 - Condition: IsEmailing = TRUE, Rule Type: Action, Run these actions: Set a field's value IsEmailing=false (lower caps)
My hang up was with the errors that it was generating after trying to submit it via preview. What I discovered is that when setting the field values for IsEmailing, I used TRUE instead of true and FALSE instead of false....arg.
I do have multiple merged cells in my form, I haven't seen a need to create a separate table for each line...yet.
Considering the large numbers of forms I have to generate to be accessible to users in a SharePoint environment, I needed to find a workaround in IP.
Thanks to ErnestoM for pointing me in the right direction, Joy_T and g21cincy for you responses and 3 cheers for Hilary!
