surface from points read from spreadsheet

hello,

i think i have a fairly simple question. i have imported a set of 9 points from a spreadsheet and i'd like to make a surface from those points. i have set my u value to number of points + 1 (10) because i believe from reading elsewhere that is what i should do. i receive the error message that the u count is not valid for this operation.

any suggestions?

files attached.

thank you,

prentiss

i've changed it so that i'm not culling the first point.

question about the u count. i thought the u count should be 1+ the number of points across (x axis). i have 7 points across and 1+7 =8, so shouldn't the surface component only accept the number 8? it accepts 5 and 7. the grid is 7 points in the x direction and 5 points in the y direction. so shouldn't the u count be either 6 or 8?

it works with the u count at 5. i just don't understand why.

thank you so much for your patience with my questions.
