1084: Syntax error: expecting rightparen

Hi folks

I am a real greenhorn here. I have just upgraded from CS3 to CS6 and had to edit a *.fla file in Flash CC. I saved it and exported as a *.swf  I now have about 40 compiler errors all of the same format "1084: Syntax error: expecting rightparen before and"

This is typical of the scenario

Location

Scene 1, Layer 'buttons', Frame 1, Line1. Column 17

1     if (_ymouse>202 and _ymouse502) {

Is it expecting a close of brackets before and ie  if(_ymouse>202)

Another example:

1     if (_xmouse>7 and _xmouse<24 and _ymouse<235 and text1.y<113

2     {text1.y_y+=4}

3     if _xmouse>33 and _xmouse50 and _ymouse<235 and text1.y>30)

4     {text1.y_y=4}

In this group, relating to Symbol definitions on a page labelled services-page it has the syntax error for Line 1, column 17  expecting rightparen before and, and also for Line 3 at column 16, just before the and.

Surely adding a bracket in that group of conditions before an "and" will mess up the "if" condition...

Any help will be graetfully appreciated!  (I can do screen grabs if it helps!)
