[Plugin: Simple Fields] Adding a new repeatable field entry using script

Hi, I am stuck with a small issue of adding a repeatable entry via a function on the front end of the website.

For example if I wanted to add content for a single field I would do something like this:
add_post_meta(get_the_id(), ‘_simple_fields_fieldGroupID_32_fieldID_3_numInSet_0’, “test”);

but when I do the same for a repeatable field ie:

add_post_meta(get_the_id(), ‘_simple_fields_fieldGroupID_32_fieldID_1_numInSet_4’, “test”);
add_post_meta(get_the_id(), ‘_simple_fields_fieldGroupID_32_fieldID_2_numInSet_4’, “test”);
add_post_meta(get_the_id(), ‘_simple_fields_fieldGroupID_32_fieldID_3_numInSet_4’, “test”);

It does not show up – I think there is a setting you have to change in the options that governs how many there are in the group but I don’t know how to alter this when doing the above… any ideas anyone?

Thanks
Jim
