Dear Netters, I'm trying to write a script that will plot a graph based on the results of population calculations. For some reason, I can't get HC to understand what I mean when I use a drag command. It keeps giving me an error and telling me that an integer is expected. My syntax is: drag from varx1,vary1 to varx2,vary2 where all four are variables why wont it do this? Enclosed is the script, the variables are oldx,oldy,newx,and newy. If you have any ideas of how I can get HyperCard to understand me, please e-mail. Repeat until Gpop + 1 = Gen put "Generation" && Gen && ": " && trunc(Opop) && Return into line nl of fld "Display Table" set textStyle of line nl of fld "Display Table" to plain put nl + 1 into nl get Mpop*(1 - (Dpop*Opop))*Opop put it into Opop choose pencil tool put Gen + 16 into newx put Opop/10 + 508 into newy drag from oldx,oldy to newx,newy *** Here's the problem. put newx into oldx put newy into oldy put Gen + 1 into Gen end repeat --NB: oldx and oldy are initialized in another part of the code and have values Gen, Opop and other variables are values from the data I'm trying to graph. Thanks In advance,
