SQL-query works on IE NS pc but not on IE NS mac

My problem is that my query on a MySql-table with php doesn't work on the Mac.

I have made a similar search-form earlier that is just fine on all platforms.

Isn't php sending pure html to the webserver?
And if the output of html where incorrect (unclosed tables, nested form tags ...), then I suppose it wouldn't work on NS pc either?!

Anyone that recognize the problem?
