the error does not match to the page you sent.
the error is saying:
Wrong number of arguments of invalid property assignment: 'WA_generateInsertParams'
/frogstyling/Asp/Confirm.asp, line 838
line 838 of the confirm page you sent is:
if (updateFieldValue = "")
this line does not use the WA_generateInsertParams function that the error is reporting the issue with.
the error and the code you sent do not match. This page could not produce that error, at least not at the line number reported in the error, perhaps a change was made to the page after reporting the error, and it is now reporting a different line number?
