Hi,

thanks for your input...

I eventually got these files loading..

i noticed a few what i thought to me to be minor differences between the layout of the working tabs and the none working tabs.

I then copied out the layout faulty tab exactly as the working tab. I then had to rename the faulty tab (with the same name) and now they are working....seems more voodoo than science...but its working so that makes me happy enough ....thanks for your help
