HI there,

I'm new to stock by attributes and have just installed 4.7a on my 1.38a Zen cart.

All looks to be working ok.

However, I wanted to do a test so I went to admin > catalog/products > proucts with attributes stock.

Clicked on Add Quantity For Product Variant and entered an amount say 10 on ALL. then saved. Then I Sync Quantities.

However, if I go back into the same attribite via the Add Quantity For Product Variant and enter another 10 say to all I get this error.

att: 5561|5559|5562|5558|5556,5678|5679|5680|5681|5682|5683|5684

Warning: Cannot modify header information - headers already sent by (output started at /home/myfoldername/mywebfolder/myadmin/products_with_attributes_stock.php:193) in /home/myfoldername/mywebfolder/myadmin/includes/functions/general.php on line 21

It seems as though regardless of the error that it still does work but as I'm new to the mod I wanted to make sure.

It still adds to the total correct amount and I can then sync with now problems.

Thanks for any input,

Murray
