InfoPath Dev

I have an infopath 2010 web enabled form. I created a data connection that submits data to a sharepoint library.

then in the Submit Options, i chose, "Perform custom action using Code" and edited the code.

In the code, i am calling a method to check if the value entered in the form is valid (custom validation)

I submit the form in CA.

when Im going to test it and i clicked the "Submit" button, the form doest close and the code doesnt work.

Does it work in InfoPath Filler?

sorry but i have not tried the infopath filler. because I  right click > design my form.xsn, its opening in Infopath designer.

When I am submitting the form, i got this javascript error. and i was not redirected to my form library

I should have been more clear - does your code work when you preview your form from designer? If not, you can run in debug to figure out what is wrong.

EDIT: Also, you can post your code if you'd like - someone may be able to see what it going wrong.

I got the code working by upgrading it. now my problem is

 Form does not close/redirect user to form library after i click my custom button "Submit"

in my submit button there is a code that checks/validates the values in my textboxes. but when I click submit, the form is submitted to the form library however the form doesnt close.

the values of the infopath form is removed (blank textboxes) and when I click my custom "Submit" button, i encounter a javascript error in my browser ("null" is null in core.js)
