exact same file - behaves very differently on PC and Mac
We sell artworks for a fundraising event once a year, and I've prepared a sales form, with a portal to line-items to select an artwork that is still available, using a dwindling value list.
On Windows 7, all well and good, the user selects the artwork, the form displays the artist, the price and the image, the user then enters the amount being paid and the invoice displays the amount outstanding.
On Mac OS 10.6.8, the user selects the artwork, the form displays the artist, price and image but as soon as they enter an amount being paid, the artwork title field randomly selects another artwork. There are script triggers in the amount fields but all they do is 'commit records' to display the accurate amount outsanding.
screen shot of relationships and invoice layout - any help as usual most appreciated
