PHP Encoding Problem

Hello, I am new to the forum and trying to solve this PHP encoding error. I transferred the files exactly as they were from the last host but had to reconnect the RSVP form to the database and it works but I get an error messages.

It reads:

Warning: Missing argument 1 for ShowForm(), called in /home/ed2010/public_html/ on line 104 and defined in /home/ed2010/public_html/ on line 236

Check the paramaters getting passed into the ShowForm() function.

Thanks for the quick response. I simply added $errors between the () and it fixed the problem with the display of the error message.
