[TYPO3-english] Adding new field to extension's table

[Peeter Rahuvarm]

Hi,

I'm trying to extend an extension's (Send-A-Card (sr_sendcard)) table by 
one text field. I've included the new field to ext_tables.sql and 
tca.php. It created new field to DB and install/database/compare says 
it's OK.  But for some reason, it doesn't show when I add/edit the 
record in BE. Are there any other things to be configured?

Thanks
