It looks like you updated code on line 1388 when I said to update line 237.
Change that line back to what it was.
You should just be updating line 237 from:
if (WA_AB_checkLoopedFieldsNotBlank(array($WA_joinLoopedField), $WA_mrtLoopCounter) && WA_AB_getLoopedFieldValue($WA_loopedField, $WA_mrtLoopCounter) == WA_AB_getLoopedFieldValue($WA_joinLoopedField, $WA_mrtLoopCounter)) {
to:
if (WA_AB_checkLoopedFieldsNotBlank(array("SAType"), $WA_mrtLoopCounter) && WA_AB_checkLoopedFieldsNotBlank(array($WA_joinLoopedField), $WA_mrtLoopCounter) && WA_AB_getLoopedFieldValue($WA_loopedField, $WA_mrtLoopCounter) == WA_AB_getLoopedFieldValue($WA_joinLoopedField, $WA_mrtLoopCounter)) {
