Hello,
I'm trying to run a series of sequences within a delay block in the DDT Food and Money so that the left hand and right hand choice will have the same starting value at the right hand side at the beginning of each block time. (ie: so the left hand side will display " 4 servings of grapes right now" and the right hand side will display "4 servings of grapes in 30 minutes").
My question is, how do I do it so that at the start of each of the delay blocks, the starting value of food is the same for the immediate (left) and for the delayed (right hand side).
Of the 3 possible food blocks I have, this is working correctly for the first two (which goes through the block of 4 servings of food followed with 7 time delays) .
My code so far is:
<data>

values.blockcount,blocknum,blockcode,values.blocktype,values.order,
values.trialcount,trialnum,trialcode,response,latency,
