[amelia] AmeliaView Error code 48

Dear all, I am using AmeliaView, and when I enter priors, I get the following once I run it in the output log: amelia(x = getAmelia("amelia.data"), m = 5, idvars = "ABBR", ts = "YEAR", cs = "COUNTRY", priors = c(27, 28, 61, 83, 98, 100, 113, 127, 128, 129, 141, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, 696.5, 1109.5, 1178, 36.5, 220, 109, 2396.5, 5625, 4625, 4625, 1261, 4.55967623933827, 4.55967623933827, 3.03978415955885, 11.8551582222795, 7.903438814853, 66.2672946783829, 2.73580574360296, 1595.88668376839, 2203.84351568016, 2203.84351568016, 3.64774099147062), lags = c("UNEMP", "NETMIGPOP"), empri = 0, intercs = FALSE, leads = NULL, splinetime = NULL, logs = NULL, sqrts = NULL, lgstc = NULL, ords = NULL, noms = NULL, bounds = NULL, max.resample = 1000, tolerance = 1e-04) Amelia Error Code: 48 There are missing values in the priors matrix. I ran one successful imputation on a similar dataset, and the only difference was the column was coded as '23' I don't know how to use 'R' otherwise I assume I could copy and paste this with the column number manually put in. Help would be immensely appreciated. Best regards, Andrew Stark
