Match function is malfunctining if variable is used as arg1

yap there are no data cause they get deleted on the menu initialization but that must be so every time its used there is a fresh set of variables. other data (that were used under the header) are of a personal character which is not to be shared....all the important data for this task are there trust me...;-)....if you click through as i explained above it will create few new entries on "krit" sheet and there raises the issue

also the columns("B:B") refers to the range where only strings are - tried out with typename function set on the variable and on the cell itself always returns string

btw. also tried to put "" to the match function (""" & choice(y) & """ ... ) didnt work either

regarding no data thats what i explain in the edit2....i thought of that problem so i skipped first set of variables to get to the point where there are data but still flawed results

Hope i´ve explained all thus far....;-)...now im off to try out the last thing you´ve proposed to declare MatB as variant which i didnt have (had it as long since the output should be numeric) but I´ll give it a shot lets see what´s the outcome....brb

EDIT: so I´ve tried to declare MatB as variant and the only result was that in debug print it gives nothing instead of 0 if i had no "set" before the actual code or

object required

error message with match. highlighted
