Mmhh .... changing the text I believe can be done via the language string override for COM_FORM2CONTENT_BROWSE.

The button style can be changed via CSS. This is the html of the button, it has a unique class.

<button type="button" class="btn f2c_select_file">Browse...</button>

OK perfect.
And if I wanted the three fields on the same line ???
DATE CREATION | INITIAL CREATION | END CREATION

Thank you and kindly as always.

Make a submission form override:
http://documentation.form2content.com/f2c-front-end/108-submission-form-templating

I tried:
I've created a standard template
I changed the standard template ... several times ...
but the error continues to come out:

Errore Form2Content : Il campo F2C_TITLE è impostato per visualizzare nel front- end, ma non è presente nel F2C Submission Form modello.

Seems your missing a field in you custom form. Did you first let the system create a default version with all the fields in it?

I've changed that.

I attach the file.
I just want the creation date, publication start and end of publication to be on the same line.

I tried and tried but the error is always out

You are missing the F2C_TITLE field from your submission form override.

The file you send me contains all the different templates..... why!?? Do you understand how the front-end submission form override works and which template is associated with it?

PS please add your version info also

I'm sorry i do not understand.
Can I write user and pass administrator ??
