Ok, this looks good but sadly not working:
I made this
the custom field exists
and I get this error message
I guess there is some wrong or "unflexible" code as the query tries to invoke hk_cat where my phpAdmin shows me this other table as the one holding the categories:
tpjtx_hikashop_category
Of course I only have means to decide the general joomla prefix tpjtx_ but no the names of the hikashop tables.
Could you confirm that is a code thing and not a bad understanding of Mas Actions from my side?
Regards,
