What's up with this?????

[Dave]

Hi,

I'm using RunRev 2.8.0.370.

I have the following in a Button Script:

   put text of field "FieldFrameCount" into myFrameCount
   repeat with myFrameCounter = 1 to myFrameCount

It has been working fine up until about half an hour ago when it  
started giving me this execution error:

Type:	repeat error in 'with' end condition expression
Object:	button
Line:	repeat with myFrameCounter - 1 to myFrameCount

I'm at a loss as to what to do to fix it!

I've tried re-starting RunRev and then Restarting the whole machine.

Thanks a lot
All the Best
Dave
