I'm trying to use hook_form_alter() to write data to a text field when the form is first displayed, but for some reason I can't get the values to display on the form itself. I know I have the right form_id, because dsm() displays all the data for that form. What's even weirder is that I can see the data being changed in the form itself, but it just won't change on the screen. I can also change the weight of the field ($form['field_class_name']['#weight']=99;) and it relocates the position of the field on the screen accordingly. But when, for instance, I change the #title and #description of the field, the changes are changed in the arrary itself (I can see this by putting a dsm() after changing the data), but the values on the screen don't change. I'm making similar changes to other forms within the same hook function (different case statements), and they all work fine. I've cleared all my caches (Drupal and browser), but to no avail. Can anyone tell me why my form data isn't changing?
Thanks.

Are you sure you have &$form and not just $form in your function declaration? I've had the same problem before and pulled my hair out just to realize I forgot the &.

Thanks for the suggestion. Yes, it is &$form. As I stated below, I'm already modifying other forms in the same function, and they are working fine.

Some other module is probably having its hook_form_alter() come after yours. Try setting your module's weight greater than all other modules and/or rename your module so it comes later alphabetically.

I had actually already done this. I'm using uc_node_checkout, and the module weight for it in the system table is 100, so I set mine to 999. Mine is the highest weight in the table.
